Check SWFA.com. They have one of the best selections of scopes. I know you are looking for a European origin scope but a scope to look at for cost would be a Leupold Mark AR and a .223 model Nikon. They will not break the bank and are very nice scopes. I have over 10 European scopes most being Hensoldt and Scmidt and Bender and Zeiss. All of these are going to cost at least 3 to 4 times as much as the Leupold or Nikon. I would suggest looking on ebay as well. Sometimes you can find a great deal on there if you look around.
Almost forgot another member on here listed a Schmidt and Bender 10 power for 650 earlier today. Can't remember who just do a search. They listed several items for sale.
