Try Tomlinson Aviation in Ormond Beach, Florida. I did my ATP(H) with them in the SA-269/300C. They also have CB models, + a real nice BIII they use for 135 opns, but they do rent it out for instruction/hour building. Very professional CFI/II's. The junior has over 1,000 (all in type I believe), and the senior has several thousand in both the SA's and the Jetranger. Both know their stuff! (386) 676-0312 phone or FAX at (386) 676-9598.

OR, try Jim or Milton at Helicopter Associates, Inc. in N. Carolina. They operate OH-6/A's which have been recertified as HU-369/500/C's. Can't find much more fun than those. They are a handful, especially to start out on, but they offer a decent price for turbine. (704) 695-1300.
