I guess I missed how this is a "true upgrade" over the craftsman 3-drawer at 1/3 the price. Rounded corners and less sturdy so you can't sit on it? I'm guessing it's lighter, but you never mention that. I'm a tool whore too, and I know the feeling of greener pastures for toolboxes, which is why I ask. I've "retired" the craftsman I got in 1996 a few times now, and yet tools keep ending up back in it. I keep wondering if there's something between the $35 standby and a Pelican 0450 that I really want but will probably...
