I'll never understand the indignant tone and accusations of greed in these threads. The guy isn't selling water in the desert or withholding food from starving people, he's selling what most people would consider a luxury item.
If he gets $35k for the machine it doesn't automatically jack up the cost of purchasing a routed Fish Tales, nor does it mean that the buyer will be able to sell it in the future for the same amount or more. Maybe the buyer takes a bath.
Some people acquired games decades ago for a fraction of the today's market price. Should they sell the games for what they paid? 15% more? 100% more? What about real estate? I paid top dollar for a property 15 years ago. 5 years later I would have taken a bath selling it. Today the home is worth 40% more. Is it greedy to sell the house for what the market can bear when there are people that can't afford it?
