I did get one model, with two cameras, one facing forward, one facing into the cabin, running off an SD card with upto 32Gb, but i did not like it... the front camera did not give enough width in the coverage, the inside camera was the same, the unit was too bulky and the 32G only worked for 4Gb, which was about 40 minutes worth of recording... the thing was about a $100...

I am checking into a full blown, 8-channel mobile DVR with hard drive recording (i have a 160Gb drive laying somewehere), with GPS, and 3G cell phone internet capacity... I have found a nice installation location for it, set up power for it and made up a harness for the cameras... i did not run the cameras yet - kids, family... you know, the same BS excuses that keep me away from a gym!!!! lol...
