Great post Bill.
One thing I would add is it is very easy for a DIY to shoot themselves in the foot. Say they save a hundred or two hundred dollars on an air pump by using a junk smog pump off a car and half horse electric motor they have laying around. They feel good about saving some money.
Only to find that the first season their electric bill increased enouh in six months running they could have paid for a proper pump that runs multiple times more efficient.
