I just got a 46" samsung lcd LNT4661f for $1499 and am quite happy with it. I would have liked to go a bit bigger in size but the larger models had a glossy screen that I knew would drive me nuts. I went with the samsung as it delivers 1080p over vga which was big for me as my xbox 360 does not have hdmi.

I have a the following hooked up to it:
-xbox original modded xbmc via component
-xbox 360 w/hddvd drive and 2 TB usb/ethernet NAS via VGA
-ps3 60gig hooked up via hdmi
-Sony DVP-CX985V 400 Disc Progressive DVD / SACD Player via hdmi
-sonicview 8000hd fta satellite receiver w/500 gig ext. (dish/bell) via hdmi

I am very happy with this setup. I have about 200 hddvd/bluray wmvhd rips on the 2TB drive, most are 720p and some are 1080p and look phenomenal over the 360. I have the last 3 years of popular tv sitcoms/dramas in xvid on the original xbox. The sonicview 8000hd reciever, its a pretty good fta pvr for the money actually, over 100+ HD channels (720p/1080i) which is awesome.

I have a 10.2 setup that is actually quite insane, i'd like to go 15.3 but the neighbors would prolly burn my house down.
