I could have cried the other day... I had a lead on a Paragon Back Glass in near perfect condition. It was part of an estate liquidation and I just had to wait for another guy to clear out a bunch of auto parts before I could get in... He was going to let me have it for free since I bought a bunch of Machines off him (non-working).
Well, when I finally got to get back to him, he let me have a bunch of small parts and some manuals, and a "for parts only" Playboy for $50... but he said the back glass had been broken by some of the guys who were moving some of the equipment around... <- That's how I fealt.
