I’m in Chester County...it’s lovely but parts are getting developed at a high rate. Some good industries still in the area and still about 2 hours to Princeton. I still love it here, though, the person that suggested the Allentown area would be ideal. Check out Bethlehem as well. I have no idea what the cost of living is like there, though. I wish you well in your search.
I’m looking at West Chester right now(really Westtown) are you around that area?
