Accecity2009 via eBay offers the Mini Spy DV 5-Megapixel 720p Digital Camcorder for $9.85 with free shipping. That's tied with our mention from last week as the lowest total price we've seen. (It's a current low by $2.) It functions as a camera, video recorder, sound recorder, and webcam. It features a 1280x960 native video resolution at 30fps, microSD slot, and USB.
Note that it requires a 220mA rechargeable battery (not included).
