I haven't had much chance to use the Turnigy cam in the last week or so, weather is on the decline here. Champ I had good luck with my FCO, unfortunately my buddy has had very little. His was a newer production run and has issues with shutting off, red/blue tint to video, and is generally being a pain. I hope you don't run into similar problems.
I'll again recommend the keychain variety of cams, specifically the 8 gig model. The timestamp is an annoying feature, if they're gonna provide it they should also make it defeatable. As I mentioned earlier it is possible to remove the timestamp from some of these cams, but you need a better understanding of messing with root files than I have.
I can offer some tips with the FCO as I used one exclusively for about 9 months, so post up here if you need help
