Sony KV-32HS500 32" Flat-Screen HDTV Monitor
Sony KV 32HS500 (The Best)
I have 2 of these, one on HDTV and one on regular cable and I can tell no difference in the picture quality, the picture is so good.    I actually prefer the regular picture because it is bigger.  It has fantastic picture quality.  If you can still find one of these, grab it.  The prices have gone down.
