I have the stainles one from Costco. It's held up great. I have some of the drawers pretty loaded with wrenches, and the second to bottom drawer is full of ammo boxes. The bearings and tracks are fine. The stainless does collect finger prints.
The newer generation of bottom end Craftsmen toolboxes are junk! I'd stay away from those. Used Snap-On and Matco are good deals, but based on my experience I can't justify spending MORE on used.
