Mushroom is correct, there a lot cheaper in Spain, I was in spain last year and bought a shooting hunting type magazine (to look at the pictures)!! But the classifieds were packed with teckels from supposed working breeding. The most pricey I saw was 250 I think.
However, as Alectoris will tell you, they are very common in Spain and you need to go to the right person. I suppose it could be like a spainard coming here for a terrier, you could get a genuine bred dog or money man telling fibs!!
