There's a store here called Frys, - I know they don't have one by you, but you could check the weekly ads at
www.frys.com or

I've seen a few times now, a complete panasonic surround setup with speakers, sub and either a reciever/dvd player or an intergrated all in one unit. I believe the price was $250.
My TV reccomendation is a bit of a different direction...
I wouldn't get one.
Instead, in your price range, I'd look for a cheap projector on ebay - I just sold my old Projector for $320, so I know good projectors exist in that price point, but it would take some looking.
Anyhow, if you want to impress the wife, then you have to impress her friends, and no 19" TV is going to do that no matter how good it looks.
My wife isn't into this stuff at all, but she loves the projector and can't wait to show it off when her friends are coming over. I just had her ask when we were getting the new one, because she thinks it would be cool to have people over for the super bowl. (We have a beautiful 50" plasma - yet she's asking about the projector)
Maybe you can't wing this, and I'd respect you all the same, I know everyone's got limits in what they can do, and to keep the peace at home, not to mention the checkbook in the black. But if it's a direction you would consider and want to know more, we're just a question away right here at the shack...
