FlightSafety at LaGuardia have both a C and a D sim and offer (as you'd expect) excellent training though not cheap. It's a single pilot a/c so you don't need a sim buddy unless you're happy to get a multi-crew endorsement.. It can be a handful single crew unless you have considerable experience... just finding your way around the Beech checklist can be a task in itself. Make as much use of the autopilot as you can.
