Video Camera Suggestion

[didjacrash]

Its Cyber Monday and their is a slight discount on the Video Cameras that you can mount on your car even above the pro shop discounts. I was wanting to get one anyway.
My Question is: What are the differences in the models, and which ones work best for drag racing, I met someone at indy this year that liked the Countour a little better than the Go-Pro.
Do you want a 170 degree lense or 130? GPS or not?
I am sure someone has some of these and have some suggestions.
