Hey. I just bought a new Canon SD300 digital camera. It came with a 16mb card standard, but right now i'm looking into getting a much much larger one. In the manual, it says that it recommends a "high-speed" memory card. I checked out bestbuy and compusa, and they have cards that have transfer rates of 2mb/s, 5mb/s,10mb/s, 60x, and 65x. Which speed would you recommend so that I could get the most (or atleast what I have now) performance from my camera? Thanks

John
