I have a Sony mini-dv and love it. Mine I believe is the DVR-HC26 model, got it for $300. It has most of the basic features like a nice touch screen, image stability, night mode etc....Tapes are relatively cheap and so far even with the constant vibration of rinding on the car for autocross runs it's been problem free. Battery life isn't the best as they rate it for 2 hours but that's if your not actually taping or using the view screen, I just need a longer life battery.
I got the camera, carry case, tripod, pack of tapes, and extra warranty I believe for about $400 together which is great IMO. Can't go wrong with the Sony's.
