David, I don't know of any commercial sources.  I obtained mine from 
Paul Otten of Natura Farms in MN.  Though he has long since ceased mail 
ordering, he does offer a limited number of "dig your own" currants for 
the local market.  So for out of state queries, I would be willing to 
offer some cuttings (preferrably as a trade) late next winter if you 
remember to bug me early next year. . .
