In 36 years of reloading I've also never used an actual "bench" as I prefer something that is easier to move.
A friend and I built a pair of these about 10 years ago using a total of 3 sheets of 3/4" ply and a a sheet of wafer board to make both of them.
The deck is a double thickness of ply with the back, sides and bottom being 3/4" ply and the top and middle shelves made from 3/4" wafer board. The base is made 2x4s and are the shelf supports.
It's very stable empty and when you load the bottom self with bullets it becomes even more stable.
It has survived 3 permanent changes of station and is easily moved by two people and is mall enough to fit in the back of the average mid size SUV.

You can just see the Lee hand press poking out on the middle shelf...
