Hey guys, just thought I would post a little note on my experience. I was selling my World Cup on Ebay and "sikicibiri" was the winning bidder. Came over with 3 guys to pick up the machine which was a little intimidating in itself as they seemed a little rough around the edges. They played the machine and I admittedly gave them an overdose of information as I realized they really did not much about pins even though this was apparently his "3rd" pinball, so I thought I pass on any knowledge I have acquired as people have and are helping me constantly.
Once the machine was purchased and taken home, I received over 4 phone calls with in a 5 hour period and then pestering for a refund as he claimed the machine did not work. He claimed he did not play a game and the right flipper came loose and was ready to create a scene , when I realized it would be best for all concerned for me to take back the machine as I envisioned future problems. When I got the machine home, indeed I tightened the flipper as it did come loose, but noticed the machine only had 1 credit in it and when I sold it I had put 21 credits on it which showed he did play it. He basically has no idea about pins and no desire to learn which made his choice of purchasing a 1978 world Cup machine an odd one as you would expect things to eventually go wrong on a machine of this caliber and vintage, so in turn have re-listed the machine. So any sellers out there be warned he will be nothing but a hassle.
P.S if anyone wants the machine let me know :)
