Should be interesting to see if a Sopranos fan steps up wanting a signed pinball machine. IMO most pinball people don't seem to place a significant value on the addition of a signature. (Even if they are fans) The person likely needs to be a huge Sopranos fan first, then pinball buyer second.

I saw that as well. It comes down to 25% if you pay by cash, check, or money order. But that certainly seems steep to me. Maybe someone with more experience in online auctions can chime in with more info.
Edit: It seems that the auctioneers aren't putting too much of a premium on the signatures either. They only estimate $3-4000.
