I have a Toshiba SD-4800 but it has several quirks I don't like. First, it drops the video signal on brightness changes. I've tried two units and they both have the exact same symptoms. It also drops the first 1/2 second or so of DVD-A sound tracks. Very apparent on Hotel California. And it has the chroma bug. I picked up a RP-91 at Fry's and I have 30 days to try it out. It doesn't have any of the above problems. It also seems well built and the on screen options are extensive and easy to use. It scales too which is something I want. The upcoming offerings seem pretty bleak. What do you guys think? Keep it or take it back and wait?
