My mid-90s Dremel kicks ass.
My mid-70s Dremel kicks ass. I'm limited to only two different shank diameters because it has a pin chuck instead of a jaw chuck, but that hasn't limited its usefulness at all. And it seems that back then the bearings had tighter tolerances - the thing runs quieter and smoother than any of the new Dremel tools I've used. It also has speed regulation, so when I load it down it slows down less than newer models. I think they got rid of that feature because too many people were abusing it and burning out the motor; too bad, because the extra grunt really comes in handy sometimes.
