LCD or CRT?

Gday all,
I'm looking at getting a new monitor for use as a TV with a new TVtuner also i'm a avid gamer. The only problem i cant decide what to get a 21' CRT or a 19' or 21' LCD. I already have a 17' CRT and I'm thinking duel monitors so can anyone give some options/opinions?
thanks

i cant comment so much on the tv tuner usage, as analog tv typically runs at a low resoultion anyhow... as far as monitor selection, using dual monitors i find is very cool (just ordered a second identical 19" lcd), that should be arriving in a few days... which equates to about 36" of usable desktop space... single view, dual view, spanned desktop,cloned desktop (not sure what the ati equivalent is for settings), for gaming, movies, general usage, etc, also helps a great deal with being able to multitask well, though the bezels dividing them may be annoying, also depending on the thickness of them, and viewing preference in general, whether that would bother you... OR, you can go for a single 21" lcd (or dual 21" lcd if you have enough money), to attain the same thing, at about 40" usable

one of the biggest advantages going to multiple monitors, is cost efficiency, ~$350+ for 2 smaller, compared to a single ~$800+ display of equal size... again, it would greatly depend on if the dividing bezels appear too distracting or not

as far as resolutions though, youre not limited entirely, theres one native resolution that looks best, depending on the monitor, but by no means are you limited to one set resolution

edit: i missed where you said you already had a 17" crt (~15-16" viewable)... identical spec'd monitors usually work best, but, just like up above, it all depends on what you can afford, and prefer... a 19" lcd would be equal to about a 21" crt... a 21" lcd almost a 23" crt (which would definetly dwarf your 17" )... so, whichever would work best for you... crt + crt... lcd + crt... lcd + lcd... ...the most affordable route of course, is to just purchase a second 17" crt

on a standard tv movies will be of normal quality pc games will be of lower quality due to less resolution however if you have a HDTV (high definition) games will be at a nice resolution similar to that of a monitor also you will obviously be able to view hd content you have downloaded on it
