The beta for PT3 is free for testing atm - but will prob be released towards the end of this month. Then you'll have to pay..

Find it at http://www.pokertracker3.com - not bad for the use you can get out of it atm.. If you want a HUD - check the forums there's an AutoHotKey hud avail - but can't tell you much about it - running under linux /macos - so wrote my own :P
