1. Used for a few transactions in my W460 rebuild, based in Germany, very efficient service. Worth giving him a try especially if you're stuck, very helpful.

2. An eBay seller who I have not used but some of their items interested me.
User ID: strafzettelsammler
Also, based in Germany with good range ofnew and used parts
I can second that, have used both suppliers, and found them knowledgeable and good with shipping, if a bit on the pricey side. But sometimes they have used parts in stock that are very difficult to find elsewhere, and not always mentioned on their sites, and I think they can source almost anything.
