Since it seems that there's no UK vendors any closer to supplying the DQ77KB motherboard, I've started considering the Continental European importers, despite the month-long delivery time, and found that the news goes from bad to worse. E.g., the Amazon associate seller "Selling IT" claims to have it in stock for £152 ($233), but that seller's customer reviews for the past month are 0% positive, 8% neutral, and 92% negative, with everybody reporting faulty goods or non-receipt and the few neutral reviews giving them credit for refunding the money. I've never seen such dire reviews -- Amazon should be ashamed of themselves for associating with such sellers. Overall, it seems that the UK's many trustworthy vendors are saying there's no foreseeable prospect of stock of the DQ77KB, and so the price-comparison search engines are only pushing the most obscure untrustworthy vendors to the top if you search for those that claim to be currently stocking it.
Any news yet about the supply from your side, Sylvia?
