Yep, and if your pops doesn't like calibrating displays, and you're not around a whole lot to do it for him, well . . . while it's a lot more gradual with the RPTV bulb, I have to calibrate about every 200 hours with my PJ. EVERYONE I know with RPTV never changes the bulb when they should. Forget calibrating.
VT25 is the best TV currently being made, so far as I know, at anything below the insane pricing of those 100" monster Panas or whatever size they are.
But, I have a screwball to throw at you. For the money that I think this display would cost, you should be able to easily get a nice 1080p projector, and I did say nice (cuz you could yet spend less for 1080p), a decent 50" plasma, a projector mount (if necessary), and a screen. Tab tensioned will be the most expensive, but the most recommended. At a much lower cost, you can use the Dalite HP as a rolldown as it is the stiffest material there is that I know (and super duper bright), and in fact you can only* get it as a rolldown.
