Thomas, all this talk about Manhatten, other communities....
You're going to work in Iselin, why not just rent a place in Iselin for 6 months or a year to either (a) see how you like it right there or (b) see what else is around.
Here's a link to CNN Money's top 10, where you can compare any cities.
Comparing Iselin to other cities
At a glance, Iselin doesn't look like such a bad place to live, or at least to rent.
From what I remember of growing up there, well, in my teens when you were more mobile, owning a car and all....nothing was very far away from anything as far as saying, let's go out to eat, see a movie, a club, etc.
Think about it. You will be spending your entire day in Iselin, will be sleeping another big chunk of time, and doing day to day chores.
The only extended time you'll have to actually go out and do anything will be on weekends, and you can travel to a multitude of places from there.
Communting is expensive. I just learned from a friend who now works in NYC, but moved back into Jersey (to take care of his father), that to travel by train costs $350 a month.....plus all that time.
Anyway, just a thought.
