Cost Plus World Market has a good one - their "HOUSE WINE" is a delicious red that's not very expensive, maybe $12 per bottle and worth close to double that. Very versatile.

For a bit of a curve-ball if there will be any red meats, etc. served then I'd look for a good Malbec (Argentina) in the $15 or so range. PM me if you want more specifics.

Tough to beat Cost Plus's "House Wine" label though. It is from "K" in Washington (state) and is consumed by the case in our household - big hit at parties/open houses.
