A summary of this lengthy post:
EstiBot.com is not at all intended to be used for determining purchase or sale prices for high-end domains or end user sales.
It is meant to be a keyword research
tool for domainers who research new registrations and low-end purchases and sales. Additionally, it provides ballpark appraisals for lower-end domains, meant as a starting point for the user's own valuation. All this is said many times on the website.
The appraisals are based on a large database of domain sales, and statistical testing shows that they have a significant predictive value. This means that
on an average, EstiBot is quite accurate, but it also means that individual appraisals may be way off, somewhat off, pretty close, or spot on....which one, that's up to the user to find out...
It's hard to please people with appraisals...more often than not, the general opinion is that EstiBot appraisals are "way too high". Especially here on NamePros that's the general sentiment. But I am also in correspondence with many professional domainers who usually complain that they are too low. That's partly because they are looking for end user prices, partly because their domains are often mid-to-high end.
Fortunately there are many respected domainers who actually tell me that the keyword reports and appraisals are actually quite good and many even send me donations to keep the thing going.
Then there are those who are in love with their own domain names (that have had no offers...) and get angry when EstiBot actually gives them a fairly realistic appraisal (IMO), which they feel is way too low...
I have considered taking the appraisals offline altogether and just leaving it as a keyword tool, but I personally use the appraisals as a quick-look measure all the time, and I know many domainers who use them too, and once you get the feel of what they actually mean in relation to the domain name, they can be useful.

estibot values it at $130! BOOYAH!
No, it doesn't. It appraises it at $4,500 if you use it right. Just read the instructions on the very landing page regarding usage with iDomains and eDomains...there are also plenty of other instructions&explanations on the site, which people rarely bother to read..
Of course, any appraisal is useless for this type of domain. Appraisals are useless for high-end domains anyway (I have always said this) but can be useful for lower-end domains as a quick-look summary of the keyword value.
An automatic system cannot know about end user motivation, and has very limited means of detecting brandability - EstiBot is mainly a keyword research tool and the appraisal is meant as a "quick look" pointer, as mentioned several times
ad nauseam on the EstiBot site
EstiBot is meant to help with keyword research, and it more often than not gives you a pretty good ballpark value for generic keyword domains, which helps users to get a starting point for their own appraisal.
A domain is worth whatever the other party is willing to pay - period! CNN doesn't care what Estibot says. If a name YOU own makes sense to a company that can in-turn build it into a 50 million dollar plus business, that is all that matters.
This is of course true to the point of being a truism.

I agree with you. I have always been a firm believer in it. IMO any appraisal is just non sense & waste of money.
EstiBot is free of charge. The appraisals are not meant to be taken literally, as said here and on the site, numerous times - they are meant to complement the keyword report and they are based on a large database of known domain sales. The average domain does not sell for $750k. EstiBot is designed for the lower end domains because I agree (and say so on the site) that appraisals are useless for high-end domains.

Unfortunately some of you are missing the most important thing about this. Often we as "domainers" go by our own bible of of what this domain or that domain is worth, and we hurt ourselves. I heard someone in another thread say, "Well, Estibot says it's only $750, so he definitely got a great deal.". Really?? To me this proves the irrelevance of Estibot more than anything (even though the creator did the best job you could do through automated methods).
Thanks for the statement in the brackets

very kind
I agree completely with what you said. I wish people would read the instructions and guides on my site, then they might say this instead: "EstiBot says $4,500, and shows a nice keyword profile, which means it may be an interesting domain and I should look into it and do a thorough, critical evaluation of the domain name", which is the purpose of the appraisal..
Statistically EstiBot is quite good, better than most humans. It often gets large portfolios right within a few % of the true sales prices. I've posted examples in my own thread and on the estibot site, of portfolio appraisals done before the auctions ended, they are very close.
A fresh example: the last 20 DNJournal sales amounted to $562,819 dollars. EstiBot appraisals for those domains amount to $588,290. To me this is a fantastic result for an automated system. However, it seems that people want individual domain accuracy, which is not possible, not consistently, not by any appraisals, automated or human.
Unfortunately, being statistically good is the best that an automated system can do, and being statistically good means that while on an average the appraisals are quite good, individual appraisals can be way off.
Apologies for continuing the off-topic digression.
On-topic: fantastic sale. I agree...Deep pockets both ends...that made this possible. I would have sold for much less....$xx,xxx
