I'll also reccommend the Mits DLP for size, cost, and PQ.
I own the
WD-65734 (bought from Amazon) and simply love the thing.
Nice thing is the 734 is a better model than the 733, and it costs $180 less on Amazon than the 733 from Best Buy.
Highly reccommend this unit.
Edit: Just thought of this; but Mits also seems to be one of the few companies staying in the RPTV business. I know that Sony recently stated they were discontinuing the line-ups, so parts for those TVs may become scarce in the long term.
