Because my state is an EPA II compliant state, I had no choice but to go with a gasser. I'm into my 3rd season with my E-classic 1400. I like my CB unit. I have no trouble with it. It heats my 1840's, 3000sqft home and DHW without difficulty. Granted, there were some growing pains along the way, but that was not fully understanding the unit and negligence on my part, nothing to do with CB. When I visited my dealer (less than 25 minutes from me) he was heating his business with one. It was January with minus temps and a heavy breeze from the north. He showed me the thing in operation. I was sold on the things. My dealer told me not be sold on one manu, that I should look at others and then decide. He likened the debate between CB and P&M to that of Chevy vs Ford. Both vehicles are quality vehicles but it's not fair to the Toyota line where they have quality vehicles too. My trouble I have is lack of time. My CB dealer is less than 25 minutes from me. I can simply jump on the highway and be there in less than a half hour. Time is a premium for me. I live alone. I work 10 hours days and some days I'm at work for more than 12 hours. I have to work a lot Saturdays too. So, when I need something (nothing needed yet) I can be back home inside an hour. If a P&M dealer was closer, I would have purchased the P&M. Am I going to sit here and say the CB is superior to the P&M, or visa versa? No! It would be very dishonest because I've never owned, operated or seen a P&M in operation. All I can tell you is my experiences have been very positive with the CB. Today I can own a Ford, tomorrow buy another it be a lemon. The same can said for any vehicle sold. Roger
