The Pilatus PC-6 Turbo Porter is my favorite single engine plane, but I would have to win the 353 million dollar lotto tonight to purchase both of us one. They only cost $55,000 brand new back in 1960's. Very versatile aircraft even used by the CIA back in the Vietnam days:

The Pilatus PC-6 Porter is a Short Takeoff and Landing (STOL) utility aircraft. The majority of aircraft are powered by a single Pratt & Whitney Canada PT6A turboprop engine, which drives a fully reversible, constant-speed, three-bladed HC-B3TN-3D (or an alternative four-bladed HC-D4N-3P unit) Hartzell aluminium propeller via a reduction gearbox. Pilatus claims that it possesses unique STOL capabilities, capable of landing in places only otherwise accessible by rotorcraft.[19] It is fully capable of being operated from unprepared rough airstrips, in remote areas, hot climates and at high altitudes in all-weather conditions. In particular, the undercarriage employed provides for high wing and propeller clearances, making the PC-6 less susceptible to damage than conventional nosewheel-type undercarriages.

Later-manufactured PC-6s are equipped with a Garmin G950 glass cockpit in place of analogue instrumentation; the majority of earlier-produced PC-6s can also be retrofitted with a glass cockpit as well. In addition to its flight functionality, the G950 system acts as a remote maintenance unit and electronic flight bag all in one. Two large 10.4-inch liquid-crystal displays (LCDs) are present, functioning as the Primary Flight Display for all key flight information and the Multi-function Display for system/mission management respectively; fully independent secondary flight instrumentation is also provided to provide backup altitude, attitude, and airspeed information in the event of complete electrical failure
