For anyone in the UK I just thought I'd add these cheap 4Gb SDHC cards to the list of cards working with the K100D (updated to 1.02, but not with 1.00, as I just found).
I know price isn't a good way to shop for cards, but I've had no trouble with a mymemory brand x133 2Gb card (currently going for a tenner when they've got stock). That's hardly a scientific test though.
I was going to stick to 2Gb cards, but my recent experience at Biggin Hill Air Fair, taking about 500 jpgs each day, convinced me to switch to PEF, which has made my 2x2Gb collection feel rather too small!
