Which DVR in-car system?

what kind of in-car system do you run? im looking at them online and they seem to run $50-200 depending on the features and price. i dont need one with LCD display or anything, just a small camera that can hide in the back of my rear view mirror and record to an SD card or something thats removable. doesnt need to have sound or timestamps either. any suggestions?

im looking at this
Vehicle Car Digital Video Camera Cam Camcorder DVR 35 - eBay (item 280327694193 end time Oct-23-09 23:21:50 PDT)

and this
Car Video Camera with 6 hour Driving Recording System - eBay (item 300354543707 end time Nov-04-09 20:59:56 PST)

but both have terrible resolution, 320x240? were in 2009 and not 2002.

Between those two, the first looks smaller and seems less obvious that you're recording video, at least it does do me. Both seem to have very low quality recording though, both FPS and resolution.

I'm currently searching for one that was designed by an individual that uses a GPS and a video interface to imprint his speed onto the video. He was hit with Ka. The citation was for much more than he was actually going. The video clearly shows he was doing much less but some over PSL. The judge lowered the fine to that of his shown speed. Later that day his wife was ticketed too but her vehicle didn't have this setup installed yet.

I'll keep looking for it, If I find it I'll post a link to it.

Ok found it
