None of these are worth more than $1k each, and some may be worth less depending on what's inside.
Folks, pricing is flat-out *nuts* these days and if you contribute to it then don't complain when it collapses out from under you. A fully-working, "players" DMD game such as a WhiteWater was about $1,200 not very long ago. Balltracks in the ramps, a bit of playfield wear, cabinet is faded, etc - but everything works and the game plays 100%, no alkaline damage on the boards, no burnt connectors, the topper is there and functional, all solenoid-driven parts (e.g. flippers) are solid with no material slop or wear, etc. How do I know this? Because I bought and owned one for a while at that price, that's how. Sold it for about what I paid for it a few years later, with decent upkeep on my part (in other words it was roughly in the condition I bought it when I sold it.)
You think any of these, in unknown condition, are worth more than that? Nope.
Nor is a WhiteWater in the above condition worth three times that much today either. It's still, IMHO, worth about $1,200 in the above condition, and while I'm always in the market for more games I really want to know where some of the folks in this so-called "market" are filling their waterglass because it has to be heavily-laced with LSD.
Go ahead and contribute to the fantasy land if you wish, but if you do it make sure you like playing the game enough to keep it forever or lose 50% or more of your money if you ever want to sell it. I have no idea when the helium will come out of you folks' heads, but I am very, very sure it will, and when it does the screaming is going to be amusing to listen to.
