Now plasma is a finicky creature...on the one hand its got great contrast, bright colors, good viewing angle. However, I have not yet seen a true 1080p plasma display...and if one exists its probably at least $5k-$7k for a 'small' 42" version. The other problem with plasma is the half-life of certain colors. Generally, I would avoid plasma, as the newest LCD-projection units are true 1080p and MUCH cheaper. If you want plasma, Pioneer or Panasonic FTW. For LCD projection, its hard to beat Sony.
DLP is the best/most affordable option, and the newest panels all support 1080p and have wicked fast colorwheels so you don't see that rainbow effect anymore (unless you have eagle-eye vision.) Samsung FTW!
The one I know the least about is LCoS. Seriously, who's really marketing LCoS displays these days? Sony? RCA? Can we get some more on the market? I hear its better than LCD projection and shouldn't have the color-wheel effect of DLP, but where can you find them?
Now onto the king of kings for image quality. Hands down, a direct-view LCD (as opposed to projection) gives you the best quality and best image, plus the true hang-on-a-wall capability that only comes with LCD or plasma. These used to be limited to 30" but now you can find 45" and even 65" LCD panels. All of these new panels do true 1080p. The only problem is cost--these are less cost effective than plasmas, but they might actually be worth it in terms of longevity. Once you're assured you don't have dead pixels (most of them you can't see anyway) then a good LCD will last a long time. Sharp Aquos FTW.
