well i payed around £300 for my heated screen, the prices are on that site, if you find one somewhere else i honestly couldnt say how much you should pay for it, roughly 3 years ago i used to be able to have normal non heated front screen supplied and fitted for £150 however i couldnt find a single place able to do that for me a few weeks back, i bonded it in with the adhesive that came in the kit i bought off ebay for fitting a screen, i cant remember what its called but the kits on ebay really are good and clear on instructions for how to do it
