Has anyone used these supposed official Sony 64MB PS2 memory cards? I only have one 8mb one and am really in need of a new one. If these work just as well I would buy one. I have heard horror stories of people losing a lot of data on a corrupted card when they use bigger then 8MB ones. Another weird thing is I have only seen these on Ebay why is that? I have yet to see one of these in a store like Gamestop or Best Buy.
