"I’ve also read somewhere else that strictly speaking dollars, if a person flies less that 125 hrs a year, its better to rent (granted, this figure is based on a certified aircraft with the owner not conducting any maintenance)."
This statement is only true if you pay actual money for your new plane. There are thousands of Kitfoxes out there, and many "deals" come up each year (not so on the RV, they are just too few and too hot to find a true "deal" on). I bought my model 4 from a widow (unstarted with the rotax firewall forward kit) for just $5000 (but don't try this at home with an RV9 !!!!). Also, you can mount cheaper smaller motors on a model 4, so you are not stuck with a high dollar factory big bore sucking avgas all day long (and your wallet)
