Hydro Thunder arcade racing games - linked pair

Selling a pair of Hydro Thunder racing games. They are two separate machines that link together for head to head play. This is a very fun and well known game, in which you are racing hydroplanes through various courses. The machines are in average to good condition for arcade games of this age. They have been nicely cleaned up from years of service, but do show typical wear and tear. They were retired from route around five years ago, and have been in my basement since then and have had zero reliability problems. All controls, lights, and everything else function as they should. Monitors both have very nice pictures. Asking $850 for the pair of machines, or $450 for a single unit. Cash or PayPal F&F. Would rather sell them as a pair. Would also consider partial/full trade for (solid state) pinball machine (working or not) Buyer to transport games. I’d recommend either a box truck with lift gate or a trailer for easy loading and unloading.
