At the risk of seeming like I'm stalking @dragonsfire
today........ I, too, am a coffee addict, and cannot say enough about roasting my own. I used to have an iRoast II, but it died a few years back, and I stopped roasting for a bit. Recently picked it back up again, and am so mad at myself for ever stopping!
My favorites tend to be from Costa Rica and Guatemala, though the best coffee I've ever had was Maui grown (IMO, much better than Kona.....though some of that has to do with the crazy popularity of Kona meaning there are lots of subpar offerings out there.) The Maui coffee scene is still VERY small farms, and small roasters.

Using the trusty air popper now:
I brew with my Aeropress, 2 cups every morning. Grind in a Barratza Maestro.
