Most of the replies have pretty much summed up my viewpoint except for one. I don't turn wrenches for a living, but I use my tools just about every day. As a casual user, I still can see the benefit of owning a better box.
I've lived with Craftsman boxes for 20 years and never thought anything of it. I never owned anything better until two years ago I bought a Macsimizer triple bay at an auction. (Caught me at a weak moment, and the cash was burning a hole in my pocket.) There isn't a day that goes by that I don't smile to myself when I open those smooth gliding drawers. To be honest, I take better care of my tools now, I think because of the box and how organized and clean all my tools look in it.
I guess if you have never owned a nicer box, a cheap one is just fine. Once you own a nicer box, it's hard to go back. I'm surprised how many of my buddies always comment on the box when they visit the shop. They think I must have won the lottery or something.
BTW, I own a Corvette too. Nice car, but not on the same quality level as a MAC or Snap-On box. The MAC is more akin to my BMW, smooth, clean, quiet, beautiful, and bulletproof.
Did I mention that I love that box?
