SD600 for a basically stripped down TM700.
HD2000 for a bit of an older one.
But I'm a fan of 60p, since syncing audio to it, is more possible if you have multiple camcorders without sync-ability. And you can tweak the frame rate to 30p or 20p for web content. And the 24p cadence isn't have bad either. frame, skip 1, frame, skip 2, repeat.
What sort of recording / battery life are you looking for? 60 minutes continuous? 120 minutes continuous? Or are most of your efforts < 20 minutes per clip?
I prefer an external audio recorder myself. The camcorder is going to compress it to AAC/MP3 or who knows what. And if you need to do some audio edits, only to turn around and compress it a second time, that is a bad thing.
