What JDM said, they are worth what the market will bear, and oh how it beareth.
Just because they might not be worth it to X-poster means essentially nothing because knukkas on Ebay pay through the nose.
Also, u mention that this is a friend, and I understand that you really want the frame, but if he is in really bad shape financially a true friend might recommend that he put it on Ebay as we all know that will fetch the highest price. However, I'm sure you can work out an agreeable sum, I personally wouldn't have a problem paying close to a grand for what u described.
