Freelander 1 Sunroof

Hello everyone . As a New member I have a 2006 Freelander TD4 . One of the last to be made of the 1 series . I would welcome advice on replacing complete sunroof . Including cassette . I do remember reading on this forum that someone knew where to purchase a new one for a fairly reasonable money ( £ 153 ) He placed the thread a couple of years ago . I would welcome his advice . I would even consider a used one in pretty good condition , if I only knew where to get one . I tried Breakers yards without any luck. Landrover's qoute was £ 685 + vat . OUCH !!!! . I spoke to my local garage ( Highlands ) and they recommend a complete cassette with motor cables . Please any help is most appreciated
