if you haven't already- post on the N. NJ board - this board doesn't get much action at all.
I live in a great town, but it's 1 hour from midtown... Morris Plains - in Morris County. VERY family friendly, safe, good schools, and on the train line.
Obviously- the closer you are to the city the more you will pay. Assuming you are going to buy- taxes will also factor in- and can vary a lot between towns/counties.
DH is a NY'er and loves where we live now. He never thought he'd live in NJ- but then he met me haha.
