What is the best SDHC card to use for the HD Hero camera? Answer: Kingston class 4 SDHC is the best that I have tested and the best price.
I tested a Kingston SDHC class 4, 32GB card vs a SanDisk Extreme SDHC class 10, 8GB card using identical cameras under the exact same conditions.
GoPro recommends using at least a class 4 card. Early on I used a class 2 card (not knowing better) during cold temperatures (7 degrees above zero) and one of my files was corrupted.
GoPro sells the Kingston card and it is the best price that I have found for that brand with a 32GB memory for $99. The SanDisk class 10 card cost $79.99 and only had 8GB memory. In my opinion, the SanDisk did not produce as good an image as the Kingston card did.
