Hey guys. I have been thinking alot lately about buying a PSP, and after reading lots on this forum I learned a lot. I am going to try to buy either a 1.5 or 3.40oe-a PSP off ebay. I have a couple questions though. What is the best way to get the most memory for the card slot for the cheapest cost? Should I just buy the official psp memory sticks, or is there a cheaper offbrand? Or what about those duo converters? I really dont know what memory I should get, but I would like to get somewhere between 8-16 gigs for as cheap as possible. I dont mind if I have to have 8 seperate cards, just as long as I can get the memory at a decent price. Also I was wondering if anyone knows how much space roughly an average UMD backup stored onto a card takes? And my last question I've looked all over for but can't seem to find the answer. If a person has a 3.40oe-a PSP, how do you convert it back to 1.5 if you chose to? Thanks in advance, hope to be a proud PSP owner soon!
