Been doing a lot of research on this. Trying to find a 19", came down to the Samsung 959 or 900 NF (apature grill), and then read the reviews on the LG Flatron 915FT Plus. It has a slot mask, it's exclusive to LG and is a combination of Apature grill and shadow mask technology, that allows for no tension lines accross the screen that all other trinitron tubes have. It also has received very good reviews. Has both VGA and BNC inputs. Has nice touch sensative buttons. And can be found for $300 (techonweb.com) or $340 with free shipping! at Buy.com if you buy 2 (that would make a nice dual monitor system).
Good luck...
Too bad I have to pay like 540 euro's (like $500) for this monitor here in Amsterdam.
