I used to work for DELL. There TV's are made by panasonic or something. The panels flat out suck. I used to have to stare at them during work. They are somewhat competitive in their price, but everytime I sold one I knew I was just selling a terrible product. I have heard horror stories. Some people got the TV's with bugs wedged in them. Alot of returns, and exchanges. Just disasterous TV's.
I was looking at the same set a few months ago. My options were limited since I was trying to fit the largest screen possible into an armoire in our living room, which meant the smallest case reveal around the edges and no speakers. After exhaustive research, I went with a Panasonic TH37PWD8UK EDTV plasma for around $1200 (stand, tv board and shipping were extra). All in, I think everything cost around $1500 or so. It is a commercial set, so you would need to also buy BIC tips (about $6 at Radio Shack) and there are not as many connectors on the back unless you add them. There is also a HDTV version of this model (the TH37PHD8UK) that runs about $1800.
It all depends on what is important to you and whether you'd be willing to put a little extra effort into the setup. I can tell you that the Panasonic displays are very highly rated, and HD on my EDTV looks absolutely amazing. At this screen size, and with the $600 difference in cost, I don't regret getting the ED version one bit (any larger, though, and I would have gone with true HD).
