Hey man, well i won't waste your time, but, i don't know anything about Air Safety, as far as westwind goes:
I called them spoke to some person there, very helpful very nice, infact when i mentioned i am from Van, Canada they said they have a flt. instructor from here with them.
So i had to call them again with further Q's. This time they were nice as usual except i din't get to talk to the admisions staff, so i left a message. Next i heard from them was 3-4 days after the message. This time when i asked where all do u guys have international student instructors, no vancouver was mentioned. Plus from the looks of it - they are a good school, but, are like anyother ordinary school, with the price of a real good school haha.
Later

P.S: Why only Arizona ? Florida is known to deliver what you want.
