I lean to the Left Bank also, but it's only a lean. As you note, there are plenty of merlot heavy Bordeauxs that are excellent, some unaffordable in effect (for me). I'm usually on the lookout for wines from a less well known region that are really good without the price. Languedoc has been pretty good for that. Spain has been good also.
Costco had Kirkland brand Gigondas for $15 each and I had to add two of those. I'll post my thoughts when I open one.
