Just a thought but if you know the part number that you need have you tried international ebay? in other words rather than the usual click here, try click here
it is suprising what you will find, i used the .com site by accident once and found side visors for my olympus eyetreck gogles. friends who have bought the goggles are pleased withere goggles on a normal day but on a sunny day are so envious of my side visors.
another idea to try is a wireless extender i saw a couple in PC world. even though you you use D-link you do not have tostay with that make and you can use Belkin or a number of other manufactureers. if unsure goto manufacturers website and ask them directly. i am sure you will be able to find what you need for a lot less than £400.
Hope this helps
