I guess I would want to pay no more than $ 2400-2500 for a 1914-1918 DWM LP-08...
The adjustable front and rear sights phased out in stages in the 1917 model. By 1918, both sights are fixed and non-adjustable.
Doug Smith and Ken Clark of FGS out of Ohio have very strong reputations amongst most collectors I know.
If you visit their web site, you will see the vast price range of the Artillery models :

Bob and Brad Simpson of Simpson LTD in IL State also have many arty offerings...you can see their pricing range as well.

Seems the dealers usually run 10-20% higher than sales between private collectors.
BTW...here is a Poll we ran asking LF members which dealers they would buy their SECOND Luger from...
