I'm in the same boat. Take my comments with a grain of salt because I'm not a TV fanatic, but, the little lady wants a TV and says she wants at least a 42" screen. So, I've been doing a lot of research lately.
What I've seen is you can get Panasonic commercial plasma's well below your stated budget of $2,000. In my case, I don't need the tuner, amp or speakers, so this would work for me. Don't know about you. I'd have to get the optional stand, and would choose the optional HDMI connection. The 42" would be well below the $2,000 dollar mark and may even be around the $1,000 mark.
Again, take my comments with a grain of salt. I'm sure more informed responses will follow.
