John-- In a similar price band to the Terrazas Alto, I suggest you try the Juan Benegas Malbec and the Luna Benegas Cabernet. Outside of straight varietals, Benegas also makes an entry level blend under their label Don Tiburcio which I think is a very strong performer. Im not sure if you can get Benegas in SFO, but sourcing these wines in EZE should be no problem.
