I'm going to have to drive down there and have a look sometime in the next couple weeks.
The stove dealer in Lexington turned me on to a company called "Lexington Forge" which set up here locally in Paris, Kentucky. They make a "Savannah" which he said is a copy of the Regency F2400. He ran one in his showroom this past winter and said he actually liked it better than the F2400. It's made locally too so that is good. They're within about $100 of each other price wise.
About the BTU and efficiency numbers. I called 2 dealers today and asked them if they could be trusted and both of them said it was pure marketing and not much more.
The F2400 claims 75,000 BTUs in the spec sheet and in comparing that number to other manufacturers, it should be a 2000sq ft class stove. The Lexington Forge claims 55,400 BTUs and 2000 sq ft capable and the dealer says they're equivalent stoves.
