[The Real Slim Shady]

Really doesn't matter. if its a casual use kinda thing - i'd go cheap. shit might take a little longer but it will get there eventually. if you're really gonna get into it, buy the best that you can afford.

regardless of the base model though - you're probably going to want to put some money aside for some better wireless adapters. depending on the type of attacks you want to perform, you may want at least 2 - should support raw frame injection and all that shiznat. and you'll probably want some better wireless antenna's.
