Thats is a good price P, i replaced mine about 16 months ago, and what a bugger of a job to do.

What i would say however is if you get the dreaded "BEEP BEEP BEEP - PRE HEAT FAULT", is makes sure you check the control module first because it is easily accesibile and you dont want o chenge the plugs onlt to find out you dint have too (Plus you'll then need to buy repladement hands, as they will probably be cut / worn to ribbons)
