The cost for housing is far better out here than as y get closer to the city.
There is also NJ Transit with the last stop on their line out here in Hackettstown so y have the best of all worlds!
Midtown manhattan is roughly 1 and a half to 3 hours depending on traffic and road conditions. Thats just to the GWB. To get down to midtown your looking at a bit longer.
I wouldn't envy either commute, they're brutal from hakettstown.
