Hello pro gamers,I am a newbie to PS3. Recently a friend told me that only fw v.3.41 and 3.55 are good for roms. So I am interested of getting a slim one for myself. However, 3.41 on ebay are pretty expensive considering most of them are used. For 300 something I'd rather get a new one. But I am not sure what version I will get if I get a new one. Can someone please tell me where can I buy a new one with v3.55 fw or older version in the USA? Amazon? Bestbuy? Target? Thank you in advance!
