Hi. I had the same issue and actually changed the screen myself using the ebay link stoney871 has posted above. Very good screen, easy step by step instructions, took me 45 mins to do and that was fitting it twice as first attempt was slightly off-centre. A bit fiddly to do if the roof is still fixed to the car but a lot less hassle than removing the whole roof. Nice little bonus too is if you send him your broken screen once you've changed it he'll give you some money back too as he recycles the zips onto new screens. Dont be afraid to do it yourself, i'm no mechanic and it really wasnt that difficult.
