I'm looking to replace the stock card with at least 16GB (32GB seems ridiculously priced at the moment) and I'd prefer class 6, although I suppose class 4 is decent. I'm thinking about either of these: Amazon.com: Transcend 16 GB microSDHC Class 6 Flash Memory Card TS16GUSDHC6E: Electronics: Reviews, Prices & more Amazon.com: Kingston 16 GB Class 4 MicroSD Flash Card with SD Adapter SDC4/16GB: Electronics I know Kingston is a good brand, and I've heard of Trascend. It's a bit more expensive, but it's class 6. The reviews seem great too, but there are always those reviews peppered in there about how the card failed after a month or two, and then I start doubting again. Any advice? Thanks.
