Around here, Kennedy boxes turn up all the time at a range of prices. The problem with deals like that is you wind up buying stuff
you probably weren't looking for in the first place. Do you really need two more 1" mics, a dozen spring calipers and some punches
and files? If you do, then it might be worth it depending on what Kennedy boxes sell for in your area. If not, then you'll clutter up
your tool box with stuff you never intended to buy and overpay in the process. Unless that's a good deal on the box alone, I'd pass.
(Or buy a roller slide equipped Craftsman and use the savings for more tools you really need.)
