I've got a little 13" RCA... don't use it much.
I get cable through my school, who I assume gets it from Charter (I think that's the local cable provider here). About 60ish channels, with a few inserted by the school to broadcast events and such.
The school seems to be on a plasma-screen buying frenzy lately, though: they're popping up all over the place (even just to display our digital signage: sounds like a good way to get a plasma TV to die within two years to me).
