I don't consider estibot a valid appraisal tool
To me as a developer, I don't look at minor speculator values, I view names as a developer
Today you need a .com for big budget development projects
You can make money in many ways with domains, but most of the old ways are dead, parking and such and even adsense.
So if you like owning lots of domains, great, now monetize them, the cost to do it with modern development makes such portfolios not that desirable, but lots of people still own lots of low value names that can often fetch minor sums
Just like lots of speculation is happening now in the new tld's
When you post a name for appraisals you need to not have thin skin, people here have their opinions and when you start to argue over a names value, it makes others not want to say anything
Good luck
