I recently bought some of these from eBay for my middy gear linkage:

eBay - The UK's Online Marketplace

Made in Germany and I have to say, the quality and finish is top notch. Maybe not such a bargain if you only buy one but I haggled and got 6 for less than £13 delivered, which I think is a pretty good deal. Good seller who responds to emails and delivers quickly too, which is nice.

Very cheap! Good for gear linkages and other non critical linkages
