In addition to the quoted price are:
Examiners Fees $2200
Written Test Fees $630
Books (approx) $600
Aircraft Rental for tests(approx) $2000
Fuel Surcharge $1500
Random Admin Fee $200
But the quoted price itself is meaningless. When you are there you're charged a rate for each hour you fly. Adding all that up simply doesn't equal the quoted price.
For the record I am currently employed as a flight instructor (my chosen career, not just hour building), although I don't teach non-US students. I know a lot about providing a quality training environment, and have no motivation other than warning people not to make the same mistakes I did.
My advice would be to find a small school for your PPL cheaply, then do a bit of flying, and visit as many schools as possible and find out what makes a quality environment for you. There are many J1 schools where you can work as an instructor, and make a decent living.
If ABA can work for you or not, you're better off finding out before you invest a lot of money in it!
