Yep, the JVC Hm100, and the newer model HM150U can record and be wrapped in .mov. I had one, using FCP, I just drag the clip into the FCP timeline without having to transcode or render, as convenient as it gets. The best thing about is not having HUGE transcoded file sizes, if I record 16GB of video from the camcorder, I import that 16GB of video to my scratch disk, drag and drop into timeline, and start editing. SO GOOD.
However, I am guessing the HM100 and HM150U would be out of you price range, if you are using imovie.
Otherwise, you will just have to deal with transcoding and getting hugenormous file sizes. 🙁
