Buying an HDTV -- suggestions?

120 Hz doesn't reduce the blur at all, you have it backward.
Actually, that's the refresh rate which is poor in every LCD out there, except the most expensive ones.
120 Hz LCD have better refresh rates, so there's no blur (and lag).
LCD are also the worst quality TV, with the worst black levels, screendoor, motion dithering, ... But some people prefer it's unnatural image, because it's more, uh, vibrant.
DLP is actually a good choice, if you're not sensitive to rainbow effect, that is.
If you want image fidelity (have the same image grain as in theaters for movies) then you can't go wrong with rear projection. But Sony Bravia SXRD (don't mistake this with the Bravia LCD, I'm talking about the rear projection ones, and not the newer slim SXRD RPTV ones which have visible geometry problems, because they are too slim) are the second best. The best are Pioneer Elite plasma for now, but that's far more expensive.
If you can find a Sony Bravia at these prices, and manage to not be sensitive to its defects (low or no green blob, silk screen effect, no 1080p@24 so you'll have judder), and can calibrate it correctly (with help from AVS if you don't know how to) then you'll have one of the best image available at these prices.
The only drawback is that I think it's more than $1500. So if you're not sensible to rainbow effect, I think a DLP will work right. Look at the JVC LCoS, they are a bit worse than SXRD RPTV, but perhaps more in these prices. DLP are definitely worse (less contrast), but still very good for these sizes compared to other technology.
