I've decided my lads 512 Pro Duo is only good for one game at a time so looking to get a 2 or 4 gig. Looked on ebay and they seem around the 15 quid mark plus p+p, they seem to be genuine Sony pro duo with Magic Gate, and refer to 'hi-speed' at 80meg transfer rate. Is this actually the hi speed version or should I look for a faster one. It's for running games ('modifed' psp obviously)
