Got a Sachs one delivered for £145 from buycarparts.co.uk, it came directly from Germany mind.
Just checked the site and they're selling the same one I bought for £78!
I bought the DMF separate from carparts4less using voucher codes, but it probably would pay to buy the whole kit. I remember there being conflicting part numbers on EuroCarParts and CarParts4Less though so double check on the Sachs website.
