As a past CEO of a group owned aircraft buying one does not save money, but gives great operational flexibility. Renting is very restrictive. I suggest stick to a fixed gear fixed prop as add lots of costs. On Lycomings if operated less than 40 hours a month they will not make TBO according to Lycoming. the camshaft lobes will wear down due to the stupid location among the other design faults. So a Rotax may be better.
