I do the majority of mine by hand and some I would never consider doing with a machine, however you can get case prep stations to make life easier. I saw this the other day which set me thinking, you can pick up a 24v DC electric scooter motor for under 20 quid, add a DC power supply unit for another tenner and you have the basis of this. Add a speed controller for maybe another tenner and some brackets and you have a handy case prep station, the thing is how many stages would you trust to a machine?
