I second this. Fresh coffee tastes awesome. I've been using a $100 roaster for a while now, only recently having got into the habit of roasting all the time (previously I'd get lazy and buy a bag at the store pretty often, which would break the habit). I need to roast every 3 or 4 days, but it only takes about 10 minutes. I don't think my roast quality is quite on par with the $17/12oz (aka $1.42/oz) bags from the store, but it's still damn good, and only like $5/16oz (aka $0.31/oz, 77% cheaper).
