While Sedo's estimate may not be accurate, it is another metric to take into consideration. After all, if you're going to take a look at Estibot why not add Sedo's number into the mix along with any other estimates. It's at least a starting point. After that, get down to some serious homework and properly analyze the name. Comparable sales are your best bet...and even they're not 100% accurate as every sale has its own unique reasoning behind it. To sum it up...it's a crap shoot!
