Guys,
The reason you couldn't find the variable speed switch on eBay is because the seller is closed through June. Check out the link.

I purchased the wiper speed switch as well as the dash mounted spoiler switch from this vendor. My main motivation was just to use some of the blanks in the dash. I have the spoiler position indicator light to go in the last blank hole but haven't yet installed it.
I believe I read somewhere the wiper switch may be available from a VW or Audi dealer. I didn't investigate so I don't know any particulars.
