Yea, from what I see from the photos...... space isnt an issue, and I would also recommend a large CRT. They have the best colors, picture, and are the best value.
The downside being they are large and heavy, but based on your photograph, you have plenty of space. You could easily fit a 65" whopper in that spot for a very reasonable cost Whoa...movie night will never be the same. Im sure the wife wont have any problem with you selling off that beautiful cabinet that sits in your future HDTVs floorspace.........HEH
