In my opinion, speed is no consideration when choosing to fly a skymaster. Safety was my only reason. If you do all of your flying from sea level to 5,000 feet, then a normal might fit your bill. You should compare the single-engine service ceiling numbers between the normal and turbos. To me, the main reason that skymasters are safe, is that right off the runway you blast through single-engine Vx & Vy. Turbos seem to fit my mission. Jim
