Main trade-off	A pleasant and capable multi-engine trainer, but the small fleet and ageing airframes can make support expensive.	A roomy and affordable entry to six-seat twin capability, but turbocharged engine reserves and ageing systems can overwhelm the purchase price.	The 337H Skymaster combines 6-seat piston-aircraft utility with about 928 NM reported range and about 169 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision.
