Agree that buying and selling is, in itself, fine; regardless of doing things to a machine or not.
If someone does a little work and cleans it up to increase its value, cool.
If someone wants to sell something higher to make a few bucks, and represents the machine honestly, cool.
I think the people who lowball like crazy buying then highball junk at crazy high prices hoping to catch an ignorant buyer is kind of sleazy. Yes, it's a free country to do so.....but I have morals and a conscience I guess. This upsets hobby people who like to see more of the fun aspects of sharing in the pinball experience.
I know people who do just this with the INSANE see what sticks prices....and they are SUCK ASS people to do business dealings with. I also, know people who buy and sell and price fair or a little high to leave negotiation room...and most are GREAT guys!
I witnessed an incident at a show where a well known pinball seller (who seems like a nice guy, but can be pricy) was being sleazy used car attitude to some uninformed people....never purchased from them again. While I was checking their games out, I saw signs noting the high price due to HUO etc on some machines...I also happen to witness a lady come up showing pics of a pinball she had in her family rec room she wanted to sell and admited to not knowing much about it. She said they had it for many years and was only ever played by kids when they were young etc. Pinball guy flat out told her that that was the worst because since game wasnt being maintained by an operator, it probably fell into disrepair and greatly lowered value. Also said kids affected it too cuz they spill their drinks (I believe kool-aid was mentioned specifically, but don't recall) etc. And make a mess of the machine causing more work etc.
He played all disinterested with the 'maybe' I could take it off you hands' attitude, while having the balls to have jacked up HUO pricing right next to her on his for sale stuff. Whether his stuff for sale was nicely redone, hidden junk, etc. THAT'S an A-hole flipper to me.
Long rant. Lol.
I think there are all kinds of people....and I don't think most people mind ANY buying and selling....just handfull of HUGE rip off prices and scammers that make many others get lumped into that group as well...
