The price of the out ring has gone up. Buying it new is probably half the cost of a used Classic. I've had an Aries 1, HW19(miii), and a Classic. I currently own the Classic and the best part about it is the rock solid barring and platter.
I found the ring clamp to be invaluable. Even if you're not in the habit of using it on every LP for every spin, it locks nicely into the Classic platter below adding more mass to the outside of the platter. That equals better momentum and speed stability.
The Scoutmaster w/ Classic platter/barring, SDS AND outer ring AND Classic arm... seems like the way to go. I'd save the shipping costs too and put that money aside. You can always upgrade later by selling the Scoutmaster AND keep all the accessories...
