£40 inc postage etc off ebay. Hardest part was stapling it on, I recycled the staples i took out, as they are shorter than those from a staple gun etc, and just pushed them back in with a pair of pliers.
Took 15 mins in total, i will get a pic of it on the car when i fit it tonight, i was surprised the knob had exactly the same fixing to the stalk as the old one did! Result!!
