For a decent $12ish bottle I like Bogle's Petite Sirah and occasionally their Merlot. I'm not a big white wine drinker, but I hear the Chardonnay is awesome as well.
I've been kind of addicted lately to Pinot Evil too. It's on the cheap side at ~$20 for a 3L box, but it's pretty tasty for being so inexpensive. It's great to have on hand if you're in the kitchen for a few hours cooking. Nice label too!
