Upgrade to fedex/ups
Pilots in the 1900 and Metro have moved up to UPS and Fedex without having to go to a 121 carrier. I don't know why people are making such a big deal about 121 vs. 135 time. It's all time in the logbook and good time for that matter any way you look at it. Pick an aircraft or the type of flying (121/135/91) that you enjoy and not just pick something that has a lot of glass and shiny buttons and be miserable.
