hiya

im planning on buying a 16GB memory stick just wanted to know a few things...

- are they reliable to use now?(for games specifically)
- i saw there are different types of 16GB mem sticks (Pro Duo, Pro Duo Mark 2, 200x 30MB/s Ultra 2Memory Stick PRO-HG Duo, etc..)...whats the difference?and if so whats the best one for the PSP for games?
- i saw a couple in Ebay, and im kinda weary on buying in Ebay again since the last one i bought (4GB) was a FAKE!!..but the low prices in Ebay makes me want to buy again :(..
