Matt, we did the propane to NG conversion several years ago, and we are glad we did. Vectron paid to get the gas to my house. I paid to get the furnace converted back to NG ($25 IIRC, heating contractor wanted to keep our account and they did several along our road). I paid the contractor to bury the line to the shop and convert the shop heater. He got carried away with the trencher when doing the NG line to the shop, snagged the copper propane line and damaged the heater. New heater at no cost. I had a gas log to convert. It seemed a little expensive, but the result was great. Yeah, I'd make the change again without hesitation.
