Hey guys, Quick PSP question. I'm looking to get the biggest memory card for it that I can find, so that I can slap a HUGE number of digital titles, as it's too fiddly taking discs around and I'm accumilating too many. However, the prices for Sony memory cards, 16gb, are still ridiculously expensive. Can anyone tell me a.) what the biggest size is for a PSP memory card and b.) does anyone know of the cheapest ones that can be used?
