Redsy,
Some people will never use the capacity of a 200A service and do not want the extra cost, I've noticed that too. I would give them the option. Most times it's not much difference from 150 to 200 though. If there happens to be a long or difficult run to the water main and there is a #6 copper in place already it wouldn't have to be replaced for a 150A service. Put that together with a long SEU run and it could mean a significant difference in price.
