Your budget I dont think would quite stretch to it anyway, but I would advise you stay clear of DVD based camcorders at the moment.
The format may be nice, ie a handy disk, but the picture quality is inferior to MiniDV, as is the recording length (at any kind of acceptable quality). The main problem being that DVD based camcorders compress the picture data quite considerably using on the fly MPEG2, but its lossy (lossy being the key word).
They have no advantage on battery life, and are pretty much a stopgap technology until micro hard drive based recorders come along.
