One day you may look back and say, "I remember when I paid only $4400 for an in demand water heater". I have a plumber that I think is pretty reasonable. I told him I had heard that there were so many plumbers and electricians planning on retiring over the next 10 years that they will be able to charge what they want because there aren't enough young people going into the trades. His response: "What are you talking about I already charge whatever I want".
