I've not been disappointed with their cutting tools, and after my last experience with K*C's service (never got the product, so can't compare)... don't feel like trying too hard.
One issue with them hiding the manufacturer is that it's impossible to see what the detailed specifications and caveats really are on complex items- you're stuck with their very limited description and a few specs. Even Harbor Freight lets you download the manual so you can get a better idea if it will do what you want. But if they gave you the real manufacturer's part number it would make it easier to shop around I guess.. still I don't think most commercial customers would bother.. it's more important to get the stuff quickly at a reasonable price than to get rock bottom pricing.
