I'm about to take the plunge too. My research has led me to think I will be getting an indoor boiler and placing it in an out building. With no doubt, a gasifier will be my next purchase. Right now, I'm leaning toward a BioMass, but EKO is a close second. I hear good things about Woodgun, but the price is too high. Tarm seems to be the leader? in the industry. The Hearth guys have a boiler room you should check out.
However you choose, good luck.
