I have the same sort of questions. I've read that plasma is best suited for fast action, ie sports which would be my priority. I've heard of image "ghosting" with LCD with sports. Would that be an issue with the higher end LCDs like the sony xbr?
Saint.......I've got a Sony 52" Bravia XBR2 and I don't notice the ghosting issue. I did have some problems with mine but fortunately, it was still under warranty. They couldn't figure out the problem for quite awhile and replaced both video boards. That didn't fix it so they had to take it to their shop. They ended up replacing the LCD panel and that took care of it. I asked the repair guy what it would have cost me if it was still under warranty. His reply.......it would be cheaper to buy a new one.......:scared
After having gone through this, I would highly recommend the extended warranty (I didn't buy it). It's pretty expensive but if I had my problem a couple of months later, I would have just pissed away over $4000.00.
As for plasmas, my wife and I really like the picture better but was advised by the salesman that we wouldn't be happy with it because we have a bunch of windows in the room that the tv is in. When you're looking at them in the showroom, look through the picture instead of at the picture and you really do see alot of reflection on the screen.
