Is this either the Regza 42XV505 or 42XV555?
If so - I have the same TV but at 37". Cracking TV - I ummed and erred for about 18 months of scouring avforums before I plumped for it (although this was 6 months ago, so I don't know what's come out since, btw).
Only thing you might find it lacking is a 100Hz mode (or M100 active on the Toshs, I think). That might mean it's not the best TV for SD sports viewing, but I've still found it fine for that myself, and you'd be paying a lot more money for anything better.
So that's another recommendation from me.
