I had one. I got it to record my dance classes. It was really easy to use, and was great for just plugging in the computer and giving the girls instant feedback, but the recorded area was really narrow. Narrower than my Canon G10 with video and the resolution the same, so I sold it. Mine also had an issue with the record button not wanting to turn off. It took several emails to convince customer service to accept it for service. You can't send it in without an RMA, and I finally had to get mad to get them to give me one, even though I had it less than a month.
Maybe my experience was just the exception. You can go to Amazon or Cnet and check out reviews on stuff like this.
