Been looking everywhere for the WMO 1.1a, but all I could find was this: http://www.amazon.com/Microsoft-D66-00029-Whe...amp;sr=8-2 and this http://www.newegg.com/Product/Product.aspx?Item=N82E16826105184 altho I'm not sure if that's even the 1.1a :(

Searched on quite a lot of electronic websites, practically all out of stock, so if someone would still know some site ( if possible belgian/dutch ), it would be appreciated!
