trying to research used prostar isx15 best atm, tc10 or ultrashift?

problem now and going forward is most fleets have or are currently switching away from manual transmissions on their new purchases. That means it will become increasingly difficult to find used trucks with a manual transmission AND all the other specs you might need. Going forward it seems like manual transmissions will become as rare and as coveted as a pre-emissions engine did. Now, I don't know how hard it is to swap an auto-shift for a manual transmission, but I personally won't be investing in an autoshift any time soon.
