Aiptek pocket web cams any good for coaster vids?

I've got $80 in Best Buy gift cards and was looking to get a video camera for taking off-ride footage of coasters. I stumbled upon the Aiptek cameras and they seem to be what I'm looking for. Reviews on amazon.com seem split. Has anyone had any experience with these cameras or know if they work well for coaster footage?

They are good but they deteriate fast. Slow frame rate, but you get what you pay for in the long run. I was satisfied for the price I paid.
