I got mine from a denmark ebayer! but think that was a one off load. Have you considered using "quidco" in conjuction with buying online from say Expansys? you get a reasonable cash back amount at least. I did this with mine on ebay and got £15. Expansys would give about 6% i think! you have to wait a few months and there is a £5 a year that comes out of your earnings! you should have a read!

just had a look, you would get £27 back!
