WEll rotories must be pretty good, there are about 29k airplanes in the world with a rotory in it, and if they blow then its hard to just pull off the road and call a tow plane, if built right and everything is done correct, then you will have a bulletproof motor. I think Kevin at Rotary Resurrection with do a complete rebuilt for under 2k if I recall, and if you take the motor out and take it to him then its even cheaper. Jsut my .02 worth
