I still love my F&S Duomatic. I don’t think a better hub gear has been made.
The Fichtel & Sachs Duomatic is also my favouring hub gear (and it suits a separable Moulton very well -- no cables). I also have a new-old-stock F&S Automatic hub put aside for some future project. The build quality and longevity is something else altogether for these hubs, plus the weight is reasonable as you save on a rear caliper brake.
