I need a MicroSD card to complement the CycloDS that I'm about to order. I was initially looking to get a Kingston 2GB (that's plenty enough space for me), but reading around it seems that Class 6 cards are recommended for flash card use. However, most online stores don't actually list what class the cards are. And I can't find any 2GB class 6 cards. Does that mean that 'class 6' is only available on SDHC (4GB+ cards)? If that is the case, then what would be the best 4GB class 6 card to get? I've read good things about Kingston, A-Data and Transcend... however, some reviews have suggested that SDHC cards take more battery power than normal SD cards. The 4GB space really isn't necessary, I just want the card with the best performance. Sorry for all the questions, just trying to clear up some confusion before I take the plunge!
