yeah the ones I flew (-100/-300) had them but I was told they were an option with the company I was with. The Dash is a good plane yeah it can be overweight at times but good for short regional routes in and out of short fields. I know the Saab 340 is faster than the Dash 100/300. Where the -200 has -300 engines on a -100 body. Kind of a 100 that went to the gym.
