A painted loading bench! You rich guys have everything. snicker.
I'd move the press towards the centre of the bench. Gives you the space for bins on either side for quicker loading with a single stage press. You put a bin of unprocessed cases on one side and empty on the other, then run all the cases through one die, using both hands to move the cases in and out of the die. You can't do that.
You can go to a reclaimed building supply shop for relatively inexpensive shelving too. Tape and mud the dry wall first though.
