I got the TH-42PX60U last year for around ~1300, so I'm sure by now it's in your price range. I shopped around a bit, before buying one, and I have to say that the DLPs I looked at didn't impress me at all. I personally found that the vertical viewing angle is very restrictive, i.e. if you're not in exactly the right height, parts of the image around the periphery of the screen, become dark and unclear when compared to the center of the screen. After looking at the Panny, I felt that the colors were more vivid and less washed out as well as having a very nice and uniform distribution throughout the whole screen. Black levels were better than on a lot of LCDs I saw.
The screen was smaller (I wanted 50", but I wound up with the 42" panny) for the price I range I was looking for, but I felt that the improvement of image quality over the DLPs made up for it.
