FYI - For anyone who wonders what is up here of if the seller is up to something Bill pretty much always deals in great high end pins and is a very honest and fair guy to deal with. Occasionally he will sell a "project" machine to make some space or raise so quick cash for other things he has going on. I have to assume he is selling this cheap just to do exactly what he said and grab some cash for another deal that is more important to him.
Anyway - top of the line guy selling a top of the line pin at are great price. I have not talked to him recently or seen this MM but I will say I doubt you will find a more honest seller. Bill is one of the good guys and anyone involved with pinball machines in Central PA will tell you the same thing!
If you have questions about this machine PM him directly and he will give you honest answers.
