The 14.2-megapixel Nikon D3100 is a great entry-level digital SLR, and at $699.95 (list, with 18-55mm lens) it's the least-expensive D-SLR to capture 1080p video. It also includes a feature no other D-SLR has-continuous autofocus during video recording, which makes the D3100 feel like a camcorder...
