What is the difference between them? Ours were pretty much like the American ones, except for they were round and had nicely styled covers.
Sometimes you can find switches and receptacles that were hardly ever used (for example in guest bedrooms) and in excellent shape. I know of early 1900s knobturn switches that still work.
There is a german company that makes replicas of toggles and knobturns that look really original, but 28 Euro for a single switch definitely isn't nice (they're available with bakellite, porcelaine and glass cover).
However, the porcelaine Schuko receptacle looks really weird! www.replicata.de
