 what's it worth?
So when I asked about recommended reading nearly everyone said Sprung and Delbeek. Because of that I've been keeping an eye open trying to find them for reasonable rates. I just came across one that is volume 1, listed as very good condition but they say some wear on the cover so let's call it good to very good. BUT...... it has signatures of both authors in it. 
So what would you all say it's worth, need to know how I did here.
