If you want to get JAA license than NAC will be good choice.
NAC's aircrafts are in good conditions, well equipped and rates are not so bad.
School looks proffesional. I disliked their fuel policy when rented aircraft is refuelled in another FBO- they do not give you full refund (maybe I just accustomed to Kansas
).
I quess you are from UK. I don't know FAA-CAA license conversion procedures, but... If you think about proffesional pilot career- another way may be faster and a lot cheaper.
