I'm planning to get a handheld console of some sorts but I just don't know much about them. I've been researching all over the web and most of the time the info. is contradictory.

I've narrowed it down between the Sony PSP and the GBA-SP/Advance etc. Which one is better?

BTW My main priority is having fun games like Kart Race etc. and probably being able to play thru the Internet for free (without getting charged for it) and possibly also which one has cheaper games to purchase...

Any advice?

if i was to buy a hand held tomorrow, i would go with the psp for sure.
