I just picked up the March 2006 copy of New Hampshire magazine, and it features an article on Our Towns, the perfect village/burb for your personality. Portsmouth, Peterborough, Lebanon, Manchester and Concord are featured. The blurbs are short, but there is also a table of helpful stats. If you could put your hands on a copy of this article, it may be helpful. Go to:

It might help give you a "flavor" of these towns.
Let me know how else I can help. I've done a lot of my own research on towns in NH, and am currently relocating to the Hanover area (actually East Thetford, VT).

I live in a 3 story house with oil heat, but with an electric hot water heater, dishwasher and dryer. This past winter our electric bill averaged around $60. We thought it would be much worse. Actually we just paid a bill of $71 but that was due to my bedroom A/C unit, July here was miserable.
We don't run the dishwasher or dryer daily, I would say a couple of times a week, but I still think that our bills were suprisingly affordable. I've never heard that NH has the highest utility bills...hmmmm. Of course, heating is another issue, but oil/gas are going to be high anywhere these days.

I just noticed you are moving to New Durham, I'm in Alton, just down the road
