That is exactly where I was at. I bought a 42" LCD Sony Bravia because the masses where going with LCD. When I divorced the ex got that set. Second time around I went with a plasma, and I am so glad I did!
Another thing worth mentioning is that if the set is to be located in a brightly lit room LCD is the way to go, but they don't look good in a dark room. The lack of detailed blacks becomes more apparent, and you will usually see some 'clouding' from the backlight. Plasmas look their best in a semi-dark, or completely darkened room.
