This question for Robert Heron, lead analyst, HDTVs, comes from reader, Mark:

I have been looking for that perfect HDTV for more than a year. Whenever I think I have found the "one," something usually throws me off, whether it's the SD (standard definition) performance, sparkly screen, or fast motion performance. Can a cheaper plasma or LCD with a great external video processor out-perform a top "consumer" $3000.00 Pioneer/Panasonic/Samsung television?

Robert's answer, after the jump.

Robert Heron: Considering that a good video processor can cost $1K-$3K, depending on input selection, I say focus on the TV itself. I recently reviewed a 42" Panasonic 1080p plasma television, and it turned in a very good performance with SD material--better than most HDTVs I've seen in the past year!

Panasonic has two 1080p 42" models now with prices well under $2k (under $1,400, if you shop around) that maintain admirable clarity with even the fastest moving video imagery.
