Oh God! Is too late I read this post. Just grab a used Zdac1 ~1 yr old for USD 350 last week. Seem like is similar to Ebay part with some better connectors and good not nice looking casing. Initially I was thinking I got a great deal, but now I know why the guy willing to give so much discount for me. But anyway, since I did not paid for full price USD875, and it still look like new, and with casing + better grade chips from Decware, it should worth USD350 and beat those Ebay cheapo.
