Camcorders, mounts, and telemetry

[— kung fu jesus —]

I am just starting to wade into this, so feedback would be extremely appreciated!

I am looking to buy a video camera for the car I can mount inside to critique myself at the track. The equipment needs to be easy to use, good support, easy to d/l and edit, and have good accessories. I am looking at the GoPro stuff, but I don't want to spend a crapload on tech that becomes obsolete in months.

I am generally do 15-30 minute sessions, 5-6/event. I would like to mount it to my roll bar. I am considering using TrackAddict for telemetry to superimpose over the video.

Ideally, I hope to have the hardware together for under $300.

What do you use? If you have videos to show as a sample (this is NOT to be a 'cool video' posting thread), opinions, pros/cons, etc. I would love to hear them!
