I have the 2 drawer husky. Only thing better about the husky as far as I can tell is that it comes with the pistons to hold the lid open. The 4 drawer husky and the black hf both come with the pry bar storage incorporated in the top, but the 2 drawer husky does not. The husky also has an extra piece of metal welded onto the bottom of the lid with the logo stamped onto it, so you'd loose about 1/2" of clearance with the top closed. Other than that they seem the same.
I only got mine cause it was on clearance for $49.. if you need a cart I'd get the red hf versions instead.
