My bench is home built, although I did buy some legs from Amazon. I think I used one sheet of 3/4" plywood and a couple of 2x4 studs.
I only have one press - a Lee Turret Press, and have turret disks for .45, 9mm, .308, and .223.
I measure powder for my pistols with a Lee Auto Pro Disk thing and with a Hornady electronic powder measure for the long guns.
I'm not a real high volume reloader - maybe a few hundred rounds a week, and it works great for me.
I do wish I had more storage space. Next thing I'll probably do is get rid of those ridiculous shelves and build something onto the wall.
