I got the Expansion board already, so I'll use that for now with the single extruder, but yes it seems the Duex is the way to go when I'm ready to uprade.
Was not aware of the PanelDue controller... I'll just get that when I'm ready.
Much thanks for your help. I dropped this for a couple weeks due to work crises, but back on it now.
Cheers,
