First off, don't get so excited with eBay prices that you pay more than the price of a new tool! The current MSRP of the Shopsmith Mark V-Powered Scroll Saw is $699.99. The MSRP of a new Shopsmith Free-Standing Scrollsaw was $849.99 in early 2008, but it looks like this may no longer be available from Shopsmith.
Likewise there have been two Scroll Saws. (Three if you include the short-lived SS mounted Hawk from RBI, shown at right).
One scroll saw was made to be powered by the Mark I, Mark II, Mark V Model 500, 505, 510 and 520, as well as the Power Station, Crafters Station and an STP Stand. The other is a self-contained Free-Standing unit with integrated Variable Speed.
By the way, we utilized the motor and speed control from a Shopsmith Free-Standing Scroll Saw to power our famous Six Cheese Nacho Cheese Fountain which is shown on our blog: http://cheese-fountain.blogspot.com/
