So now that they're FINALLY producing 1080p 32 inchers with 120Hz, I think it's time to pull the trigger on a TV, seeing as I haven't owned one for 2-3 years

My Dell Ultrasharp is great, but I can't watch cable on it, and it does some terrible stretching to 1920x1080 sources.
So I've been looking at an LG, Samsung, and Sony, has any one had experience with one or more of these? Which one has the best picture? I can stare at a spec sheet all day, but the only one I've actually seen was the Samsung, which looks pretty good.
Any thoughts?
