Anybody have any sources for non-biased equipment reviews/comparisons - aircraft, avionics, cabin eqipment, mods - for turbine equipment? We are considering an aircraft upgrade - BE-B200 to a BE-350 or possibly a midsize jet. I've tried to search some magazine sites that have those type of articles - looking for an index to pull up specific reviews. Not having too much luck with ProPilot or Flying. Also sites like Aviation Consumer are geared towards the piston ranks. The aircraft spec site on AOPA was good as a performance comparison. PlaneQuest gives a relative comparison to operating costs (although some figures are real low) between aircraft.
