Grigg, now that's a deal on a air compressor for $150! just as long as you got the room.
It's inside now, but to save some room I'll make a lean to shed sort of cover for it with doors on the front and plenty of ventilation. It'll go outside against the shop wall with a plug in on the wall and an easy to undo hose connection. Then to service it I can pick up the whole thing with the forklift and bring it inside if necessary.
