Which Tv Should I Buy?

[Carnage311]

Well, I am about to buy a new tv and I pretty much have it narrowed down. The only problem is that I can't decide what size tv to get, so I just thought I would ask you guys since I can't decide. All three tv's are Samsung LED DLP tv's and all three do 1080P. The sizes are 50" for $1,688 shipped, 56" for $2,005 shipped and 61" for $2425 shipped. My problem is that while I can afford the 61" tv, my logic and common sense says that the 50" or 56" would be great and that it would be stupid to spend $500-$1,000 more for 6-11 more inches of viewing pleasure. I could take the money I save and buy a good surround sound system, hd dvd player, or just save my money. I can afford to do all of this anyway it's just that my common sense says to get one of the smaller tv's and save some money. What do you guys think?
