Bill,
It all depends what type you are thinking about. The cheaper ones are not true slots. They are designed to accept tokens, Have no arm to pull and you have to push a button on the front to stop each wheel from spinning. There are modified ones that will accept quarters, have the "one arm bandit" and will stop by themselves. This type will run from $500 to $800 and is the type I have. The real Vegas slots can run from $88 to $2000 or more. I can only tell you that anyone coming to my home can never resist playing. We have many hours of enjoyment with it. To me it was well worth the cost. I keep mine set at 94% payout.
