The unit to get is the Oregon Scientific ATC3K. It has 4 Gig storage capability. This SHOULD be the one that RAP4 is selling, BUT ASK! (It looks like it in the picture) The ATC2K is only 2 Gigs storage. You can find these elsewhere but they won't have the gun mount or barrel mount. only a bicycle type slide mount. Most cameras have the exact same specs but this one is the best deal and most compact. As far as the audio goes, this camera IS WATERPROOF, so it can have paint splats washed off! Once you put a membrane in front of the mic, it will have a tendency to be a bit, well, muffled.
