After staying on 3i to the end, wondering if I would get my past due RVN's (I did) we were transferred to Virtopia that had the exact same non-payment issues.  I waited for 21 hours or so for payments to come through but they did not so I left to go to Ravenminer.  Ravenminer worked perfectly from the start; I guess I have found a new home. 

Virtopia, about 26 hours from when we were switched by 3i paid out what seemed to be owed.  It seems as if they, despite a less than auspicious transfer of the 3i miners, have finally brought themselves current.  It seems as if they are a responsible pool that makes good on their past due coins.
