I know this is an old post but have you tried emailing around the UK retailers?I was in a similar situation for months,and after having contacted Dye Europe and RAP4,I was about to throw the towel in and buy from the United States.I had a little nosey around the like of LIPS and FatBobs,but they didnt have it showing online,so I emailed them out of curiosity.I got a reply from LIPS and FatBobs saying they had some instock.I bought mine from FatBobs as it was a few quid cheaper,and possibily the last one in stock.Get in touch with LIPS as they may still have one,that is unless youve managed to find a kit.
