well, the t-bot is working good so far.. you can minimize and hide the game from windows, and you can se the details (hp,mp,how many killed,coordinates etc) on top of the screen.. it's pretty good, if you want to play other games, because when it's minimized, it won't take much cpu
the advantage of isrobot is, that it's pretty easy to configure and to use...
you just need the coordiantes where you want to bot, and the bot goes the right way, and knows where trees/walls are. On t-Bot you need to record a "script". that means you have to show the bot which way he has to go.. pretty confusing...
about the prices.... both are kinda expensive xD
i like both the bots.. atm i'm using t-bot...
