My experience on PSP Street White E1008

[TkSilver]

The psp models for Aisa should be 1-Japan 5-Korea 6-Hong Kong and most of SE Aisa 7-Taiwan and 9 - China
E-1008 should be a Russian and former Soviet block countries

Also really only the PSP 1k series (the first ones) should really make a difference in performance since besides some motherboard revisions the main specs didn't really change much between the 2k or 3k or go or street.

Also at least where I live in the US it would be very hard if not impossible to find any new PSP systems though I think Europe might be a little better.
