I am trying to decide between four models and have to make a decision by the end of this week for my new home.Trim carpenter is building entertainment center and needs the dimensions. Any help would be appreciated. 1. Toshiba 50HDTV 50H72 MODEL BEST BUY PRICE 1709.92 2. Pananasonic PT51HX42 MODEL BEST BUY 1708.92 CC HAS ON SALE FOR 1583.98 3. Hitachi 53UDX10 WHICH WAS RATED #1 BY CONSUMER REPORTS IN MARCH.The only scary thing is the store only has the floor model left and they will have to order the remote but they have marked it down to 1766.99. Should I buy a floor model? 4. Samsung PCL5415RX 1599.92 AT bEST bUY WAS IN THEIR FLYER THIS WEEK.
