No beating a good Bordeaux, in my book.
If you want value, look for smaller wineries and read for good reviews. Remember that wine is made from fruit and the taste and quality will vary greatly from year to year depending on climate and rainfall. You might get a great product one vintage, and the next year may be only mediocre.
Also, don't force yourself into thinking that wine must be from France or California. I've had some excellent bottles from Australia and South Africa, and a couple of really nice pinots from Washington and Oregon.
Now, Tennessee on the other hand. . . . .
