Latest results of my quest for the elusive DQ77KB...
There's a UK-vendor price-history search-engine that lists the DQ77KB called Pricespy , so I've ploughed through the websites of all the vendors listed. These were all out of stock, but some give a stock eta two weeks ahead, which has convinced me to wait a couple of weeks before trying an expensive importer, but I might discover that a "2 week eta" is vendor code for "no eta but I hope you'll keep checking my store".

Two vendors listed it as being in stock: "Mavit", which has no web existence beyond its website and claims to be a "Google Trusted Store", but that seems to be false because Google says the "Google Trusted Stores" are USA only at present. And "ITX Warehouse", which also has no web existence beyond its website except for a single negative review at reviewcentre.com by somebody that had to make legal threats to get a refund for an incorrectly described item.
