As I said before all the other parts are on condition.
Hiller Aircraft still makes Hillers. Pulse sells refurbished helicopters by United Helicopters in Florida.
Mr. Selfish, how can you say you never want to fly one, if you don't know anything about them. They have an excellent safety record. Hiller has a high-inertia rotor system, which gives you a lot of time to lower your collective iin an engine failure and it's a breeze to make a zero-zero full-down. If you pull collective to much you will ascend again.
The Hiller is the only helicopter (without hydraulics, sas etc) where you can let go of the cyclic and it will just continue. (Not that I do it by the way) Stanley Hiller demonstrated this once by trimming the aircraft and then climbing out to the engine deck and staying there for a couple of minutes.
