If you mean the one Herb designed based on the Vario Clipper, when it stopped being offered in the Western Hemisphere, I think it's the best you can get. You can still get the original Vario Clipper from Europe, but it will cost even more than Herb's, due to shipping and taxes.
The Vario Clipper (or Herb's) produces a very precise cut, without the variations of other choppers. People have written in describing ways of avoiding these variations, but they do add time to the chopping process.
