i recently purchased an extremely cheap alternative on ebay. its a keychain covert spycam. I velcro'd this to a sunglasses case and onto my sun visor. It can record up to 2.5hrs with the 8gb mini sd card in there. It also takes jpeg images with the push of a button. I usually turn it on when I start driving, I don't do 2 hrs of driving on a regular day so its good for small local commutes. Its a DVR so the file format is avi and can playback on my cell phone on the fly. I can delete, modify etc.. had it for a month now and pretty content.
