If you're serious about your coffee, or think you might be, go lurk for
a while at alt.coffee

They know more about coffee than you could imagine. Most are into
espresso, but they'll give good advice on "regular " coffees as well.

The first and easiest steps to making great coffee are buying fresh
beans, and grinding them for the coffee you're going to make now.

ALL pre-ground beans are stale in a few hours.

Grinding your own has many different cost levels, but you can start low
and grow.
