I don't have a tv, and would like to be able to use my old PS2 so I was considering getting a LCD monitor with a TV tuner. I'm looking for a 22" monitor in the sub $300 range, but I can't find any with a tuner. Do the tuner cards work as well as the LCD's with built in tuners? I'm guessing the computer would have to be running in order for that to work, instead of just the monitor? Is there anything else I should know about them, or is there anything special I need to get a PS2 to work with one? I don't know anything about monitors or how the tv tuners work, so any help would be appreciated.
