I restarted collecting pins about 3 years ago. I bought a few new pins over the years, but missed out on some great titles for lack of time, focus and money. Now I have time and money. Besides the outrageous cost of shipping, buying games on eBay has turned out to be fraught with hazard. I have bought 15 older titles now and in every case but 3 of them, they arrived with various degrees of problems. The latest example was a short on a Breakshot that the prior reseller had obviously spent considerable time trying to trace, but had finally given up on - and decided to dump on eBay. Although a top rated seller on eBay, the problem was not mentioned. It was subtle, but would have been discovered if I had flown to his location and played the game for 15 minutes.
I now have most of the titles I wanted, but the true cost of ownership going thru eBay (after shipping and hidden repairs) has averaged an additional $1,200 per game. Fortunately for me, I know an expert mechanical/pin engineer to help me when I get a troubled pin.
I have decided no more eBay games - only locally available games and new games. That means my collection will probably never have an Attack from Mars or Doctor Who or 'The Shadow' -among others. Auctions are a reasonable alternative, but the games I have bought at auction, that we're not totally refurbished, are 'run out'. They never work for very long before requiring repairs. My HUO games and purchases from collectors have been worth the premium.
