Now, this is interesting: Very little info around about this box yet, but I found a Thread "elsewhere" in Greek, stating:
ναι AC3+/DD+ και ειναι ενα μεγαλο συν σε σχέση με την octagon
which Translates as
yes AC3 + / DD + and is a big plus compared to the octagon
So I'm awaiting an easy source of supply and tempted to get one.
