I have my Lee Classic Turret (and the board it mounts on) in a plastic toolbox about 23" long. Seven sets of dies in turrets in another, smaller toolbox and powder measures, scales and miscellaneous tools in another. Highly portable.
With a Black & Decker folding workbench, I can set up anywhere in about 15 minutes and load as conveniently as I can at home. No extra press needed at all.
Just the way I do it.
