Lead,
Shuttle America has their maintenance base at FWA (Fort Wayne Indiana) and they only have SF34's here, as to acquiring regional jets I haven't heard any rumors.
From a controllers stand point the pilots are pretty good to work with, our only wish is that the SF34 would climb faster so that we wouldn't have to point them out to the next facility that is over 40 miles away. They are supposedly dropping their contract with US Air so we don't know what they have on the back burner.
