do your research ,but I think you will find Mesaba is one of the better regionals out there,its been my experience that I have been treated as a person not a number,the training is first rate,quality pilot group and well maintained aircraft...the only part missing was the growth,but now that has changed I dont think you could find a better place to go right now.
Ref fly's message,he is right on the money,I have flown both and I dont regret my time on the Saab in fact coming from a GA backgound I think it made me a better pilot...and after all it is ALL turbine time,and you will get a chance at a jet eventually,its my guess that in time some of the older saabs will go away to be replaced by more crj's
good luck
