Your best bet is to watch the WTS section on this forum and the one on the luger gunboards
http://luger.gunboards.com/
The guns in the range your talking do not last long, so be on your toes and check often.
There is a Finnish Luger for sale now but a little higher in cost, it would be a good buy and make both a collectible and shooter.
They make great shooters as many have already had their barrels replaced.
