Aerokit sill covers: where did you get yours?

[damonbill]

I have a non aerokit 996 c2, and want to fit the aerokit sill covers (996.1 aerokit to be pedantic, the car is a 996.2 but I think the 996.1 sill covers look better).

Looking around, OEM or even aftermarket are very expensive, even banged up 2nd hand ones go for £250 per side on ebay. I've seem some cheaper fibreglass ones online - but does anyone have any recommendations on where to source reasonably priced ones, or have tried a fibreglass alternative and are happy?

any experience / advice welcome!
