I'm definitely investing in an arrow press and ceramic burr grinder soon (anyone have any experience with Hario?).
As for trading I have access to a myriad of local stuff, Blue Bottle, Ritual, Four Barrel and Sight Glass as well as Sweet Maria's for unroasted beans. I'm will to trade with anyone interested in trying any of these companies coffees.
ISO Stumptown FT various Bay Area coffees
Man I miss Stumptown so much...
Hario is a hot brand among coffee-loving hipsters, and people who have the Hario grinder say it’s very good.
AeroPress does make a good cup of coffee, but I don’t use it because I avoid plastic wherever possible in making coffee. Personally I prefer Chemex or a French press, or espresso if you have a good grinder and machine.
Coffee peaks a few days after it’s roasted (when it's doing a lot of off-gassing), and then gradually gets stale, so if you don’t know when it was roasted, you don’t know what you’re getting. (The general consensus in the coffee world is that green coffee beans last for many months; roasted beans for a couple of weeks, and ground coffee for a matter of minutes.)If you’re going to have beans around for more than a week or two, I think they’ll hold up better in the freezer, but that’s controversial among coffee enthusiasts.
If you don't have a good local source for coffee, most of the specialty coffee vendors sell on-line, including some mentioned in this thread like Blue Bottle and Stumptown. Also excellent are Intelligentsia in Chicago, PT’s in Topeka, and George Howell in Boston. For equipment, almost everyone's favorite vendor is Chris Coffee in Albany, NY.
The coffee equivalent to geekhack is coffeegeek.com – if you think keyboards can be a pricey hobby, avoid the reviews there of high end espresso machines as well as the forums where people discuss equipment and technique for roasting your own coffee.
