I kicked around the idea getting one of these big ol' 4:3 HD RPTV (the bigger model of this same line though--the KP-61HS30!) If the convergence and guns are all set right, they can look really damn good. I decided against, because I wanted to use the same TV/Monitor for LD as well as blu-ray and these RPTVs only have component as their HD inputs (no HDCP compliant digital input for blu-ray.) That and they're really damn big!!
However, if you're not planning on using it for blu-ray, I imagine it'll kick a** for LD and DVD (and HD television content as well.) It has the same 16:9 enhanced mode for anamorphic and HD content that the WEGA line has, and you can definitely see the difference in detail when that is used. And if it has the same 3D comb filter that the HS/XBR WEGAs do, it works wonders with LD (it does have a 3D comb filter.)
I remember a thread on another HT forum where this one guy touted his HD-ready Sony RPTV after getting guns cleaned. Showed screen shots of the Superbit DVD of
The Fifth Element and it looked really damn good.
So it's worth a shot. And it's not as heavy as I thought it would be--157lbs.
