On the advice of Devil5052 (to another forum member on a different model) I took the ride to New Bedford, visited Rene at American Energy Savers and purchased what seems to be the last Mark l this side of the Mississippi. For the record, I'm an Car Sales Manager at a store that takes a huge amount of pride in being the anti-shyster dealership. I can vouch for Devil when he says Rene is a top notch guy. Not only was his price $125 less than any other quote I received, regardless of whether a unit was in stock or not, but he tagged and held the unit for me without taking a deposit, even though I offered one. Very easily could have jacked up the price considering the latest Harman press.
I want to thank Devil and everyone else on this forum for all of the help and advice. I look forward to sending my hard earned money to the fine folks of Pennsylvania and to continued support as I get up and running.
If everything pans out the way I have been told by my coal burning friends I will out the door with the unit, all materials and a winter's worth of coal for less than what it would cost me to heat with oil. Incredible.
