I will be selling a Whitewater machine in the very near future - probably will be ready next week.
Good - plays really really well. Above average playfield. Fully working. Strong flippers. LH-6 ROM.
Bad - I would look at replacing the Disaster Drop ramp at some stage. Display has some faded lines on initial start up - they come good after about 10-20 secs. It has a topper but it is very faded - a decal from Treasure Cove would sort that out. Cabinet has some chunks out of the decals here and there.
I need to take some decent pics of the machine which will be available soon.
I don't know where you are located and what sort of dollars you are looking to spend but just get in touch with me if you're interested. I am happy to help out if I can.
