I owned shares in a DR300/140 and a DR400/160. They were both astonishingly capable with a build quality I've yet to see on a light aircraft outside the Beech factory. I enjoyed having a stick rather than a yoke, but that may be due to the fact I fly Helicopters as well. I do remember that the nose attitude in the cruise seemed very low, but that just enhanced the view.. IFR they were a delight, and the left hand throttle felt very right with a stick.
I flew the 400/160 to the Atlas mountains and regularly took it to Greece. These days its a 182, and while I like it I would go for one of the new Robins any day.
