Yes, their price is reasonable compared to other offerings without the EFI. However, I fly all conversion engines that I get for free or nearly so. I have a fleet of 10 airplanes flying, and only one purpose built gasoline engine; a DA-100. All my other planes have converted Echo, Stihl, Homelite, and Ryobi engines. If it were not for conversion engines I could not afford to play in the gasoline engine arena.
