The Sony Wega 42" LCD is the largest LCD panel i am aware of. It is not cheap. Like all LCD panels it suffers from response time issues, but this set does have very fast response times compared to previous generations.
Plasma panels, 50" and over (though I am not yet aware of any products over 50") are not light. The weight of the panel increases in proportion to the SQUARE Area of the panel. The weight increase is actually MUCH worse than that, because the thickness of the optically clear glass must be increased as well to provide the necessary structural integrity. Costs climb amazingly quick after 50" for large thick panels of optical glass.
The 50" LCD displays being bantered about for around $3k are RPTV's.
