No Autopilot seems to very fashionable amongst BE1900 operators, "why bother, we pay two pilots anyway".
The Canadair Jet is available without FMS and I think some have been delivered. Doesn't make sense for Europe anymore.
Our Dash 8s only got FMS in a "last-minute" effort before BRNAV regulations took effect. Our old flight operations manager had the opinion that you could fly any direct in our route network with conventional navigation and "rule of thumb" as well, so why take the cost :-) (We used to carry homemade tables with all the directs required, cross-bearings, etc. and it actually worked quite nicely. Some guys carried handheld GPS but it never really worked because of the shielding in the windshields. Having done this for quite some time I really noticed that you lose some situational awareness when you let the FMS do the job, especially on longer flights.
Before you flame, I DON'T advocate a "return to basics" approach, I probably just remember a time when I was younger :-)
