For what it's worth, my current instructor here at Monarch began his training at Spartan and he told me he hated it.
He said that he paid 15,000 for his PPL alone before saying "screw it" and moving down to Dallas where he finished his ratings here at Monarch. Plus, Tulsa is not exactly the greatest place on earth for many people. My fiance is from there, and here family still lives there.
I cringe everytime I have to make the trip...but some people like it. Oh, and my Instructor said that on top of all that he had his flight bag stolen out of his truck while up at Spartan! Headphones, logbook, equipment...all gone! He spent 1 month going through all his receipts filling in a new logbook!
I would say be careful with Spartan. While I don't have personal experience with them I know many who do, and I have yet to hear a complete satisfied story.
