I asked the clerk what the difference was between
the two.... he said the colour of the case and the price. Bob would have
bought the yellow case.... I bought the orange one. ;-D

I'm afraid the clerk is wrong. Dewalt still uses different motors from B&D and
are rated for a longer lifespan. That said, I probably use tools far more often
than you. Some people still work on their boats for fun, rather than paying for
services. You probably don't even polish your own hull!
