You may want to try some of the South American malbecs. They sell for around $10/bottle. Significant tannins but a lot of flavor. The French use the varietal to add some body to some of their blends. Bodega Norton is just one readily available vintner.
As a matter of fact, speaking of Malbecs, we had a case of Trumpeter Malbec this last spring; very good with lots of aftertaste. I think Trumpeter is Argentinian, but I could be wrong about that.
I've got a friend who raves about Syrahs and Pinot Noir, but they're just too light for me.
Found a couple of good Zinfandels: Ravenswood, and Habacho (?, not sure of that name) (another South American goody).
