HF Model 67980 has a built-in DVR, stills or video, internal memory as well as an SD slot, and the camera head is 8.5mm dia, it also comes in a nice fitted case. I just stuck the camera down the barrel of my 9mm and took some lovely pictures. At any rate the 67980 definitely gets an A++ rating. On sale now for $219.99 and I had a 20% coupon as well.
