Especially with no feedback here thats a hard sell, but good luck.
I have a 60GB PS3 on reserve that is "supposedly" coming before Friday from EB so I stood in line a bought a 20GB from Target. The wireless I could care less about,the card reader is worthless to me and the larger harddrive is pointless because I'm going to throw in 100GB drive anyway. Unless you really need that wireless just keep the 20GB.
