No, I'm not. I guess on PokerStars I figured I wouldn't run into the same people enough since its so big, but it's probably worth it if it helps you stack someone once. Just been using Poker Tracker. On sites like Ultimate Bet I see the same people all the time, but haven't seen a lot of the same face on PS.

I have plenty of desktop room with 2 24 inch widescreen CRT's (they are insanely cheap now) so I'll grab PokerAce HUD. Thanks for info!
