I have 3 types of psp, but still loyal gihapon ko sa akong phat.
PSP1k
Pro: More Durable, can be used as pandora (use to downgrade and upgrade psp), way problema if ma brick.
Cons: Heavy, because daghan siya ug pyesa compared to 2k, coz iyang LCD has metal frame, dako pa ug gap sa screen, kung imong kuptan di dyud ka maka ingon ordinary toy ra.
PSP2k
Pro: Lighter and more memory, bit faster, has video out (PSP1k can do that using CFW)
Cons: You fee like holding a toy, feel nimo ma bali nimo ang psp, klaro kaayo nag cost cutting na sila kay walay metal frame ang PSP, battery is not pandora support, rarely you can find a stable version for brandnew units.
I have a stripped out psp 2000, nga pwerting gaana coz I remove the UMD drive, samot feel dyud nga murag toy pwerting gaana.
For more details whats inside the PSP read my thread.
