Thank you for your reply. We already have Conklin and deDecker but it doesn't say pilot and operator experience. Your advice is exactly what we missed in our puzzle. The aircraft will be operated from middle east Germany and as I said half and half in Europe range and to the East. So XLS is out due to its range. G150 would be good choice but I'm afraid it's out of our budget. Hawker is a little bit expensive for variable cost than L60 and G150. So in 600 hours per year it can cost a lot. There is no more choices I guess.
