My wife bought me a Oregon ATC2K camera for my birthday, which I'm looking forward to playing with, but she didn't get me a memory card to go with it. I plan to pick up a couple of 2Gb SD cards which should give me 2hrs viewing time.
However, when searching the net for places to buy said cards, the choice is massive and it's not clear why some 2Gb cards are £10 and other apparently similar cards are £50. What should I be looking for in an SD card for a vidoe camera? For example, is £21 a good price for a SanDisk Extreme III card?
Sorry for all the questions, but I'm totally clueless when it comes to this sort of thing

Thanks,
John
