Yes Vale the SAAB 2000.
Drop down masks in the cabin allow it to cruise above FL250 in RPT, and achieve that with little effort also. Mighty aeroplane born at the wrong time. Ideal today, but probably with a fleet mix of the drawing board bound SAAB 340C (Standard SAAB 340 airframe with all the 2000 gear and performance), and common crew endorsement.
I know that REX have approached SAAB to look at starting the line again, but as time draws on, it seems this will be very unlikely. Pity!
