Here are the words from the RCBS web site:
If you own an RCBS Rock Chucker, Reloader Special-3 or Reloader Special-5, you know they're some of the finest single-stage presses ever built. The Piggyback III conversion unit moves you from single-stage reloading to 5-station, manual-indexing, progressive reloading in one step and moves your output from 50 rounds an hour to well over 400. If you own the new RC Supreme, the Piggyback 4 is the unit to convert the press to progressive. Optional extra Star Wheel can remain permanently attached to the Shell Plate for quicker caliber changeover.
Have any of you had experience with this new unit?

Swifty,

I have a nieghbor who does custom commercial loading for a retirement income. He aquired one of the units you mention here at a gun-show used, at a reasonable savings over new. However, while it does work satisfactorily, he wishes he'd either gotten the RCBS 2000 progressive or another Dillon press.

The unit appears very well designed however, and runs fairly smoothly.
