AH Bot General

[DrGonzo]

I notice there are a lot of autoit AH bots floating around and I was wondering what sets of features differentiate them. Are any of them inherently different besides price or this a symptom of "me too" ?
Other than the obvious what kind of features do you guys look for in an auction house bot (please don't say things like randomized click positions and timers, that's just silly)?

-filtering of all stats on items
-throttle search queries to a human level
-only bid on items with no current bid
