In my humble opinion,
I would highly consider your local FBO, depending on side and quality of aircraft and instructors. I have had the opportunity to try all. I was a member of a flying club in my teens, attended UND, and later finished my CFII at American Flyers and ATP at ALL ATPS. My MEI at the local FBO.
What I enjoyed most about the Flying Club and FBO is the atmosphere. Less stress, not an overwhelming desire to get you the door with the minimum required experience or completition standards. ( I have a problem with guranteed and what that gets you.
Cost wise it may be equal or a little cheaper, you will have to draw out that sheet. However many FBOs offer a discount when purchasing hours in Block. And you can get financing with out having to attend big name schools. Check out Pilot Finance, and AOPA flying Loans (though MBNA).
While you may find the syllabus more detailed at the schools you can have a very well outlined plan locally.
When you are done you will be most likely wanting a job, both can offer this. The big name school may hire you if a position os available and you performed well, you can also pick up a job at the local airport.
However in my opinion the networking potential at the FBO, flying Club could me more. You are meeting all walks of people flying at the local airstrip. Airline pilots, corporate pilots, wealthy individuals with their own airplanes etc. At the big named schools you are teaching the same type of individual that were, a person looking to get their tickets, and then teach there.
At my FBO I am helping one of the MEIs try to get on with American Eagle. Another CFI become good friends with one of his students who owns a A-36. He now gets to use at whenever he wants for the price of gas.
The big name schools are great, do not get me wrong, however I really enjoyed my time at the local airport and people I have been fortunate enough to meet and become friends with.
Any other questions feel free to PM me, I head out on 4 day trip tonight but will bring my laptop.
Good Luck and happy flying.
