I know this is a loaded question..were purchasing a p61 in Dec. The p68 is backorder until Jan. Only 1 month. We have a 2000sqft split level home in the fingerlakes. Insulation added to the attic newer windows. Stove will be located on 1st floor over bedrooms. Would you stick with the 61 or is the 7k btu p68 worth waiting an extra month for? Thank you!
