I realise that this thread is a little old but I thought I'd pipe up anyway!
I have just fitted some black ones from ebay to my 2007 (sorry it won't let me put up a link?).
They are chinese but work a treat and look really good in black (I can post a picture if you want?) my only gripe was the nut that came with them is aweful! I ended up using the nut that came off the stock indicators and it worked a treat.
I should say that they have only been on a week so I can't say at this point how long they will last but fingers crossed! And for £40 i'm not too bothered.
I hope this helps?
