Try the Epic Trail Cam.
I received one of these as a graduation present. I currently have been using mine to mount onto my helmet at ww2 re-enactments for 1st person coverage and also at paintball games. However, now that i'm going to start OCing i think this will be perfect for my needs. It has great audio and video and can support up to a 4GB SD disk. Only downfall is that it is an outdoor camera only and needs plenty of light. So indoor locations are usually dark and fuzzy even with lights on. I saw mine in the store and it was $150. runs on 2aaa batteries and comes with easy hook-up for a pc or laptop.
