Email the folks at D&M Liquor
in San Francisco. They specialize in French booze, and can tip you off to some amazing stuff at different price points. They have great customer service, and will put together a selection of fine brandies for you after you explain what you're looking for. They also have great "of the month" type clubs for armagnac, cognac and calvados. I've subscribed to their champagne club before and it was worth every penny. I've also had them assemble half-case samplers for me, which is a great way to get a broad introduction to different representative styles of a particular spirit.
