If you need a newer, thin display, check out the Sony KDL-55EX640. It's a 55" edge-lit LED with Internet apps, and comes with the wi-fi USB dongle in the box included, but you can just simply not use it or toss it out. While it has an ethernet port, wi-fi is not built into the set itself.
The LG LM5800 may be a better option. 55" edge-lit LED with passive 3D without any smart TV features or wi-fi.
