I used to very much like the Gato Negro wines that I could get in Washington State. At the time their wines ran around $3/750ml bottle at the grocery store. This was years ago, and no doubt the price has gone up, but I'd try the label again if I were to see it. I remember a red (merlot? blend?), but I think they also offered a white that we liked.
Edited to add: I second kayb's recommendation of the Bota Box Pinot Grigio.
