I will say that I've not had any HF tools that suck lately, but then I don't purchase any of their low buck stuff anyway. Always the higher priced tools.
One of my favorites in the Bauer corded finishing tool with the interchangeable drums. It allows me to change out drums for removing mill scale on ferrous metals but at the same time, removing oixidation from aluminum prior to welding (by changing out the drums, something you have to do when going from ferrous material to non ferrous material simply because if you don't, when welding aluminum, a ferrous drum would compromise the weld. Actually have my drums marked as to their use...and the Bauer tool is quite a bit less expensive than the competitors as well.
