I have heard figures of a million bucks or more to get a tower up and running. First of all, seldom do the companies (Verizon, Cingular, etc) build the towers. The sites are acquired by third parties, they do the legal stuff (like "yeah, coverage is bad here, but no tower in my town), finally get the approval, build the tower, and then lease space to the companies.
Maybe once the Wolfeboro airport closes totally, they will get a tower up on Wolfeboro Neck (great for the lake and parts of Alton Bay that are hidden from Prospect Mt). Oh, I forgot...while it may make sense, who would want the tower in their McMansion's backyard or even neighborhood.
