Jose, are you looking for real vending machines for gumballs, or a novelty item? Genuine Eagles are expensive -- I sourced some a few years ago used, got a lot of five used "gas pump" style ones that had been refurbished for $3,000 plus freight and it was the best deal I could find online or off.
Those at CandyConcepts, that are down in the sub-$200 range new, are about the cheapest ones you can hope to find, if you're looking for something that is an actual vending machine vs. a piece of home/office decore that looks like a vending machine.
