Thanks for the good info.

I guess the real reason for my post is mostly to get a sense of the
construction cost difference. It'll come into play as we weigh all the
other factors that you and others have already mentioned.

Contractors are reluctant to talk dollars unless we have blueprints,
but we don't want to pay for blueprints until we know which way to go
on this issue.

We feel we're in a catch-22 situation. Just trying to get a sense for
some of the info that has elluded us.
