I received my JVC RS-20 (Same as HD750) 3 weeks ago and have been using it daily since. I find that it is quiet, throws a beautiful image, and really haven't encountered much of a downside. In terms of negatives: There aren't dedicated input buttons on the remote (you have to switch using an input button). While the lens shift of +/- 80% vertical and +/- 30% horizontal is great, I could use slightly more, but then again, 80%/30% is pretty good. There are some forum reports of trouble dialing colors exactly into specification. I don't have a colorimeter, and happily use the factory-calibrated THX mode so I can't comment on that. These are nitpicks for a very nice piece of hardware. Reccommended.
