I've also had experience with Colgan and found them to be a good honest company. I had a great time working there. People were great and the flying was fun. I got great experience, was able to upgrade quickly, and after three years moved on to a major airline. Like any company I had one or two minor issues. But I was never asked to fly when I thought the aircraft was unsafe or when I was fatigued. Try to stay out of a NE maintenance base (Albany and Hyannis), unlike SAAbaroowski. That will keep you away from the part 91 ferry flights.
Once I left Colgan I found that major airline captains, a large number of which came from civilian ranks and flew turboprops themselves, very respectful of SAAB drivers. My transistion to the 737 was a breaze.
Good Luck! Have fun.
