I searched but didn't see a thread that really corresponded to my question.

I don't have much wine knowledge or an educated palate; I just know some of the French wines I've enjoyed in the past include

a good Muscadet to accompany seafood
Pouilly Fumé
Tavel
Bandol
Saumur Champigny
Sancerre rouge
Beaujolais Villages
Côtes du Rhône
St. Émilion


Now I'm in the US and have no idea where to start! Based on the "profile" above, can you recommend any wines available here for under $20?
