737-300. At the time, I had a couple of buds at Southwest that told me the company didn't care if you got the type in the old jet or the new one. I called all the sim companies, and Aeroservice was the cheapest. 20 days in Miami was fun as well
I did the written through Sheppard Air's gouge. Highly recommended. Used them for my CFI, CFII, and MEI Military Comp test. Great folks.
