I'm selling my DAS Model S Ultimate keyboard on eBay
http://www.ebay.com/itm/121344350404This is the 105 key ISO UK layout with blank caps and Cherry MX blues.
It's seen some fair use since I purchased it 8/8/2008 and it was my workhorse for a couple of years. There are some scratches and shiny caps but the board itself is sound. No liquid damage.
The board also has 2 USB ports and comes in the original box. LED lights are actually green despite showing as blue in a lot of literature and even on the box. Product details can be found at
