I'm running an ATI TV Wonder with a Hyundai L70A 17" Flatpanel. Image quality is pretty good. Just as good as on a CRT (which means it's not quite as good as a standalone tv, but not much worse and definately watchable). The only drawback as that you have a more limited viewing angle than with a CRT (be that a CRT monitor or tv). I'm in a dorm and sometimes I like to lay on my bed and watch tv. That puts my computer screen at an angle; I can still see the picture but sometimes I have to move around a bit. Just a warning if you're going to use it at a tuner but won't necessarily be sitting in a chair in front of the computer to watch it.
