I flew the Beech E55 & B58 all over South Africa. Operated out out mine air strips in the main. Most was hot & high. Best piston twin I've ever flown. If you want turboprop there is not much to beat an Aero Commander.
The Baron is rugged and tough yet built like a Bentley. If I had the money etc - it would be a 'no brainer' what I'd opt for.
