Saving for a 220 now! I am getting one for sure.
Just out of curiosity, what for? Are you going to send mics directly into the PIX220 and bypass the recorder for easier syncing?
Right off the bat, this would replace a 702, fumbling with tapes for the camera, and post transfer capture all in one box. Feed your mics to a V2 (as in Mark's case) if you don't like the preamps and feed the video image so you don't have to deal with the dvi capture during transfer. Then it's just a matter of a minor resyncing of audio if your mics are not near the camera.
To me, if there was a Staples Easy Button for video/audio recording, this would be close to it.
