Buying a flash card for my sister for Christmas. Not sure what to get her. she's wanted one since i got my CycloDS Evo last year. but i dun want to buy her a cyclo since that's a little too expensive. any idea's on what would be a good choice. something with good game compatibility. and supports SDHC (8 gig). features such as RTS and slow mo are not necessary since my sister calls things like that "cheating". any suggestions?
