I'm assuming that's true LOP, GAMI'd & Deakin'd?
What do you think?
I am not sure about a golden age. There is a lot of R&D in the "cheap" end but a suprisingly small amount in touring aircraft. Cirrus & Diamond are now old hat (and unless you particularly want a diesel irrespective of reliability, a TB20 beats both of them), the Lancair is no good for grass so very limited for Europe, there is the Czech VUT-100 which is
very much like a TB20 and which is slowly coming along, and...?
But if you have £1M+ then you have plenty of turboprop choice. But, that's been the case for many years. The jets are the only new thing, and IMV they bring no additional mission capability over a turboprop.
