Quoted from planters49:Expect to pay at least 1500-3000 more at a retail shop than if you buy something from another hobbyist
not necessarily true (depending on your definition of retailer). I just bought my lethal weapon (everything intact, nearly perfect playfield, minor dings on cabinet, no damage to light topper), $1100. Even though pinside rates it slightly lower, I see them on CL all the time for between $1100-$1600.
It's a guy that runs a business out of his home, buys/sells/fixes pins (it is a legitimate business, he charges tax). I guess he can sell a little more fair not having overhead of a store (everything is in his garage workshop), but still.
There are certainly two different types of sellers. Those that truly love the hobby (and don't pay themselves nearly enough for their time of acquiring them, fixing any issues), and deliver a great product. And if there are issues, they will be very explicit about them (even if they are minor).
Then there's the "flippers" (no pun intended) who will lowball sellers to get a deal, then turn around and sell a machine quickly that isn't working for top dollar to ignorant buyers. Fact is, you'll find those people in any industry (car salesman, realtors, etc).
