I use a Solis Maestro burr grinder, a Braun drip coffee maker with a thermos carafe, and Trader Joe's brown paper filters. So I'm picky, but not a fanatic.
For the last few years, I've been using a 50-50 mix of Peet's 101 and Sulawesi-Kalossi, which I arrived at after some years of experimentation.
They recently raised their prices a buck a pound, which I found really annoying given the state of the economy, so I experimented and find I like 101 + Garuda just as well. But that's still $13 a pound, and I'd rather pay less if I can find something I like as well.
I don't care for light roasts. For example, Blue Bottle's darkest is way too light for me.
