I dont think any auto-tool is 100% accurate but this is among the better ones however I think because of the hyphen in the domain it undervalues it more than it should. It gives the non-hyphenated version a price of $89,000 and this one only $900 - Thats way too big of a deduction in price just because of a hyphen IMO
Update: I have a $200 offer for this domain but I really prefer to sell it via Sedo auction. As said before I will accept the $60 minimum bid there for it.
