I just called Etronics to inquire if the Yammi 1400 was in stock. Salesman said yes. I asked if the unit had the DPL IIx feature and he told me no, they hadn't received the updated units yet. I thought I read somewhere on this message board that someone recently purchased a 1400 from Etronics and it did support DPL IIx. Did you happen to see that post?
