Just have to say, this thread is great. I've looked for years at the roasters at Williams Brewing and thought that it was just too much of an investment for something that I might not stick with.
But after reading this thread and the info at Sweet Maria's, I'm heading down to the Walgreen's at the corner to buy up a couple of their poppers (if they have them) and give this a go.
Lucky for me, I just piped an outlet on my back porch, so I've got an ideal spot to roast and let my neighbors deal with the smoke and chaff!
