I just picked up a used PS2 from a friend for cheap but it didn't come with a memory card. Where's the best place to get a cheap one? Best Buy has one online for $19.99. I was hoping it would be $19.99 in store so I could get it for 14.99 with GGC but no such luck. I'd prefer the Sony brand as well. What are peoples opinions on the non sony brand memory cards? - thanks
