Any question answered...

I would like a rear rack for my Raleigh town bike, the one I have at the moment is a creaky, squeaky, wobbly piece of shit, and I think some of the threads are fucked which means every time I grease and bolt it it just petulantly spits the bolts back out and starts creaking again. Now I'm living where there are cobbles, I can't stand it any more.

It needs to be black or silver, sturdy as an ox, fitted only using a rear brake mount and mudguard eyelets, and not be too expensive. And preferably available in a shop in Berlin/German mail order site.

Any ideas?

If by brake mounts you mean cantilever brakes, Old Man Mountain racks are probably your best bet. Mail order across country lines and even oceans is easy these days, and for me usually half to two thirds of the local price. (I will pay local if it's HERE, but the item almost never exists out here in the hinterland, and most LBSs are loathe to do special orders)
