Yes CRT's are generally less expensive than LCD's for the same sive TV. They offer better blacks, but are limited in size. They alo weight more and take up more space.
If I was in the marketfor a HDTV, I would try to wait about 6 months. A bunch of new companies have entered the Plasma/LCD market. Also established TV companies have increased production and facilities (Like samsung, lg, panasonic). What this means in about 6 months or so the supply will be greater than the demand so prices should fall.
