I just got back from Binny's, where the wine guy very unjudgmentally pointed me to the Cuvee de Pena. It's one of the more expensive boxed wines ($30 for 3 liters) but it's rather nice for a boxed wine.

It's a French vin de pays, a blend of Grenache, Carignan, Syrah and Mourvedre. So far, I'm liking it quite a lot for what it is.
