Don't laugh. I'll put it up against Glen Ellen or even another good everday wine, Concha y Toro's Cabernet.
On weekends, we try other stuff, but nothing over $10-$11. Just finished Nominee Cabernet from Paso Robles Wine Co in San Miguel. Other good stuff we like is Calama Cabernet from Chile and, of course, Rosemount Shiraz or Shiraz/Cabernet from Australia. All inexpensive and quite good.
For white, we drink Cavit Pinot Grigio in 1.5 l bottles, at $7.25 from Sam's Club. We also like Buena Vista Sauvignon Blanc, Hogue Fume Blanc, and Meridian Chardonnay.
The 2000 Rosemount Shiraz is an excellent deal. I believe it got a "90" rating in Wine Spectator (for what it's worth) and it's not often you get a "90" wine in the under $10 a bottle price range and it's available everywhere. Well I think it's pretty good and I'm already working on my second case. Another favorite wine of mine is the Rancho Zabaco Zinfindels (California).
