I have owned both Spacedecks. I can't say positively what 4yanx says is true. I have only heard the taller platter version with the Ace-Space, and this combination is a nice improvement over the original Spacedeck/Spacearm combo.
If you can get a B stock table with the Ace-Space for $2400.00 like you say, that would be the better bargain than the used one with the OL arm. I had that same arm on the Spacedeck, and even the original Spacearm is a better match for that table. And I think the new arm is better still.
