The problem with NJ is the courses really suck. You have legit bums teaching the courses. The best place in NJ I went too though was Gun 4 hire. You should head into the city though and go to andy massimillians place, I haven't been there in forever. Since I travel a lot for work I take all my classes while traveling for work at places like Gunsite, Thunder Ranch, Rogers shooting school, etc.(front site in LV sucks, don't go there).
That said, if you ever want to take some good courses in the north east, you may want to take a day trip the sig sauer academy in NH or Academi in CT. Those are the 2 best I have been too in the north east(and I have been to the vast majority of the "famous" ones).
Also, there is some place(I think its hoboken, or the town next to it) that has some range that has some Ex Mossad guy teaching a pistol class. I have heard really good things about the course, but I never bothered to take the course, since I am not a fan of not keeping 1 in the chamber.
