The Bauer option wasn’t available when I was making my selection (it was far enough back that there weren’t that many at the time), and it took a while for drawers to become available:
(note that that has since been replaced by the “real” drawer units — I still have a bunch of the Harbor Freight organizers, and I’m debating on either filling them w/ Gridfinity bins, or using them for Lego bricks)
I really hate the idea of a bottom unit which can only be reached via unstacking (in retrospect, storing all my sharpening stuff in the Husky one was a bad idea).
At some point, I’m going to have to break down, lay out a couple of tarps, empty out all the toolboxes and take everything down off the pegboard, then systematically re-arrange the tools — maybe if I can figure out what is suited to be in the bottom unit, I can make that work — if not, I my need to update to something like @Redlander has (if memory serves, the Rigid system has an option for a bottom unit which has drawers).
I only need a couple of additional tools, mostly larger ones, and I believe that I should be able to integrate a shooting board (which is one of the tools which I need) into whatever setup I work up — we’ll see.
