Thank you for having the desire to look for a Lava Wave Machine. I have all of the wave machines from the 1990's my uncle Jeff had until he was killed in October 2008 and they were discontinued in September 2008. I inherited all dual color models, atlantis, new LW line, Adriatic and Caribbean and several Carlisle wave machines. Hughes saved my Wave Machines by filling up all wave machines, adding a small air bubble, putting one color to fill half of tank and another to fill the other half, and adding bubbles on the bottom waves including dual color models, adriatic, and Caribbean models. Fortunately, all my wave machines black ends and the tank didn't leak or crack except I put flex seal tape on the black ends to protect it from leaking and put scotch tape on the plastic tank. The motor still works.
Unfortunately, I am not selling my wave machines right now.
