I want to shot 16x9 video at the "best" setting with my K7 but my sdhc card will only give me about 48 seconds before it automatically stops recording because my SD card is too slow (PNY Class 6 8GB). If I go down in quality, I have no problems recording much longer. I know the best is probably the Sandisk Extreme 3, but if I don't need to buy that fast of a card, I'd like to go for something less expensive! That's why I'm asking you guys. If I need the Sandisk, than that's what I'll buy. Tell me your experiences, I'd probably go with a 16GB or 32GB card???
