Try the rosenblum Annettes vineyard reserve. Bevmo.com has 6 of them in stock at $25.
I bought a case of the anette's and they are really nice (and the price is excellent imho).

I also liked the carla's vineyard (and it's a little less at $19). Really nice zin.

If you get a chance i'd plug the Niebaum-Coppola directors reserve zin. I think it's excellent. In fact i like all red wines from niebaum-coppola's directors reserve and estate lines. The zin is $27 and worth it imho.
