To be honest, I am not sure. He said make an offer, and I bet he'd take 1-200. The thing is, I could buy a 45k Mr Heater (garage is 600 sq ft) for about $400 and get a warrantee, an owners manual, the install experience of dozens here, etc. I am afraid with the Janitrol I am rolling the dice and hoping it works. Or am I making too much of this?
