"You could always pick up a cheap Lee Reloader dedicated to de-priming and make a tray primer catcher like mine."
The little tray is neat but I made my revision even simpler. Mounted my Lee "Reloader" on a 9" piece of 1x3 oak, bored a 3/4" hole under the press, mounted the lid of a pill bottle under the hole for spent primers. Bolted the oak block to the bench top so the bottle is easy to reach and remove. That worked so good I got a second "Reloader", and put a Lee Auto-Prime II on it, mounted it some 6" or so from the decapper. Love that system! And it's VERY easy to do with common tools, a piece of scrap hardwood and a pill bottle.
