I have one of these:
http://www.hobbyking.com/hobbyking/s...ory_card_.html
It is out of stock there, but I'm sure similar could be found on ebay.
Scroll down on that page for customer feedback/reviews and links to video's on youtube.
I've only used it once but it worked great, and for only $12, can't go wrong.
BTW, the weight listed on that site is the shipping weight, not the camera. The cam is about the same size as my thumb and weighs 20grams. They are listed on that hobby site as people put them in their radio controlled planes.
