Let break Scott's globe down. $350-$400 for gill body leaves $450-$500 for lenses... meaning $225-$250 per lens. You could ask Scott if he would take less. Let him know you only need one lens... maybe he has someone else only wanting one lens but doesn't want to break it up. You never know.
If you got a real good deal than you could if needed to pay top dollar for a single lens then.

Looking for anything from Hoosier Pete, Platolene 500 and Red Bird.
