Those lower lip spoilers...

[YZF600R]

I would like to get the lower lip spoiler that I see a number of people have as I think it finishes the front of the car nicely.

However, where do I get one? I've found them for £220 so far but none in stock (from MX5Parts.co.uk). I have trawled Ebay for a few months but apart from replicas have not found any!

Any pointers? Anyone got one for sale?
