I have had good luck buying from Zu eBay. They run promo auctions and you can get some real values. I got the Ash digital coax cable for $50 plus shipping (MSRP is $249 for 1m); they raised the minimum bid right after that.
They don't have an eBay store front, but the seller name is zu_promos. This is mentioned on their web site too. Even when buying at a discount on eBay their service and support are superlative. They reterminated a pair of speaker cables for me when I changed my mind and decided to go with bananas on amp end and spades on the speaker end...this was at no cost to me other than shipping the cables back to them.
I've tried a number of cables from Audioquest and Kimber and found that Zu meets or exceeds the better known cables at the same price point and in most cases at the next model(s) up. I'm in the process of converting all of my cabling over. Zu reperesents an outstanding value.
