Rickyboy,
I would guess that the price of any gun would vary from country to country. The below Swiss "Cross in Sunburst" is pretty much the going price for one with a good holster and an appropriate magazine.

In my limited opinion and observations, finding a Swiss Luger in good shape is relatively easy because the Swiss are,on the whole, the best in the world at maintaining their weapons. Even though there are probably Swiss Lugers in bad shape someplace, I have yet to see an ugly Swiss Luger. Because of their usual condition, they are all prizes.
