On the other hand, for America's birthday, you should have American wine.
14:42 had a good suggestion if you can find it. (The Petite Syrah/Petite Verdot blend from Michael David.)
There are many quality Zinfandels in that range, from Turley Juvenile (about 22, if you can find it and it's not marked up--saw it in Bell's on M St.) to Plungerhead from the Lodi area (about 15). Anything with the word "Rockpile" in it (a new region in the Dry Creek Valley) is also going to be good.
