Fall 2008 was when oil shot up and we went looking for a supplement. We decided we wanted a furnace and it was really down to either Harman or St. Croix. Harman looked to be on 4 month backorder according to the closest dealer. St. Croix Revolution was also on backorder, but it was only six weeks. Went with the Rev, probably could have used the slight extra BTU output from the Harman, but the dealer seemed uninterested in pursuing anything he couldn't sell right away and didn't even have any lit available. The St. Croix dealer at least had a SCF-050 so he could show us about what it would look like, and promised to deliver a Rev before the snow flew, so he got the sale.
