Can't beat the GoPro for the money, but beware it has an extremely wide lens. It's 170 degrees in 720P mode. I've used it on a 450 heli for areal shots before. I'm not sure how your software will deal with the fish-eye perspective.
You can look into the cannon elph line of cameras, I use an old 5mp one and it does great. You can find them on ebay as cheap as $20. Mine is an sd450. The elph line is relatively smaller than other digital cameras. Haven't looked to see what new stuff they've come out with lately.
the problem is that I really don't need a screen, or zoom, or even a case. I just need a quality sensor with a normal lens, a shutter button and a microSD card.
I guess if I can't get that, I'll have to figure out a way to mount a bigger camera. I've finally reviewed some roll-stabilized footage from my 808 camera, and I don't think pitch stabilization is necessary at all. So ideally i'd find something small enough to mount on the micro servo I already have installed:
I was hoping someone would try the aftermarket GoPro lens and report on it. I like the gopro but it is just too wide. Look at this footage (shot on my HFP X-8). It's waaaayyy too wide. It looks like you can see the curvature of the earth.
Just thought I might share a bit about the little Staypro 45G Pen Camcorder at Xheli for only $49.70... I know the price shows higher but when my wife ordered mine this is what we paid for what ever reason...

It shoots 720p which is1280x720x30fps... From all I read it has sharper imaging than the Keychains, although there is a new 1080p Keychain that is suppose to be coming out, or maybe is already out, that could be a real contender if it works...
I do want one if they are out because there really is a big visual advantage to true 1080p which is 1920x1080 resolution over the 720p format of 1280x720... If it has good optics, exposure, sharpness, saturation, and a decent menu system I want one...
The internal batteries on many of these cheap-o's are a bummer and many have poor quality charging problems yet others swear by them as working perfectly... Many have to be factory reset all the time from lockups and many require tinfoil shielding due to our ESC's causing noise interference that shuts off the recording as happened on mine... Each purchase is a risk though on these cheapies and even if you read the GoPro reviews some have problems with them too at $300...
Here's a video of my little $49.70 Staypro 45G... Ain't great and ain't bad I guess... Also a couple pics of my mounts I built for my Multiplex FunCub... The video was taken with the Staypro Velcro'd onto the side of the fuselage...
