Well I returned the Aiptek today. Too many audio problems and no ability to use an external mike. It also has some weirdness if the camera is moved during filming too much. Overall the video quality is ok and you don't need a super powerfull pc or a 24+ inch lcd screen to edit the video.
At this point I will most likely choose between the Panasonic SD1 and the Canon HV20. I would have liked a decent camera/vid cam like the tx1 but Canon ruined it with the Mjpeg codec. I will probably end up with the sd1 since I'm stuck with a 8gb class 6 card and tape noise seems likely for quiet indoor filming.
