The JVC Everio offers several models. Probably one of the most appealing thing about the everio is that it records to MPEG2 (uncompressed DVD) instead of MPEG4 (highly compressed like a digital camera's video). Its resolution is also DVD resolution 720x480, however it is more like tv quality (interlaced video) and less like digital HD.
It is offering a JVC Everio GZ-MS100 model right now for $180, which is really nice, considering that flash memory will continue to get cheaper. So instead of paying $350 for a hard drive camcorder... get a flash based one, and get a 2GB SD card. In a few years 8GB and 16GB SDHC cards will be cheap, and you can just use that for your camcorder.
For accessories it might be a good idea to get an extra JVC Everio battery. Because even if you have space to record 4 hours of video on your SD card, it doesn't mean your video camera battery will last that long
