the biggest reason not to get a dvd camcorder is that there is no way to copy the info from the camera to the mac. the only way is to rip the video from the dvd, and that reduces the quality by too much imo. like said, i'd get a minidv camcorder, and most panisonic, jvc, and sonys work with the mac. just be sure to check the imovie camera support web page before buying.
