:lol::lol: If the OP doesn't mind it not being an actual tv and they're going to use it via HDMI anyway, they could always just buy a 20-25" LCD PC monitor with an HDMI out for $200 or so and use that.
That's what I'm using my PS3 with currently, though you may want to get an external sound system for whatever you're using it with since the speakers on those are tinny(if there's even speakers on it at all).
Or....you could check Amazon's website, as they have some 20" or so LCD tv's for $200-ish. But a 30" tv for $200 is a pipe dream unfortunately unless it's a refurb or otherwise messed up.
