[nowornever]

Hi,
I m frm pune.I am going to buy PSP soon.Ihave few queries and expect help soon...
1)Can anyone tell me where can I buy PSP cheaply whether in mumbai or pune and shop details as well?
2)Is it worthy to buy from grey market considering the warranty and originality of product as well?
3)I don't want to spend on UMD ,so from where can I go for modding my psp?Please provide me contact details either from mumbai or pune,but preferably pune and rates as well....
4)What if I go for memorystick from manufacturers other than sony eg.sandisk etc.Does it make any difference in playing games/ compatibility issues?
Cheers...

1. There are two shops on MG road near Arora Towers who sell modded PSP, they will ask for 500/- to mod but you can bargain. Price of un-modded PSP will be 8500/- there.

2. Warranty is void you mod the psp to play your game backups without UMD.
3. see the answer to the first Q
4. using Sandisk 4GB with no problems.

Hope it helps.
