Yep, that Marrietta is very good. Consistent quality too year to year. A couple others that are widely available and inexpensive:

Ravenswood Vintners Blend Zin
Bogle Old Vines Zin
Rosemount Shiraz - although I can't remember - either the 2002 or 2003 is not up to usual standards
D'Arendberg Stumpjump Red (Shiraz/Grenache/Movedre blend)
Artesa 2003 Napa Chardonnay
