Need help with values. Have a guy here locally who has these three machines for sale. Wants 300 for Playball, and $1,000 for all three. I don't think the Playball is worth more than 200. All three are sitting on the floor and may or may not have all the legs. All plug in and light but make serious bad noises. The cabinet on Playball is rough at best, the backglass looks pretty good, but playfield not sure because it is so dirty. All three have been sitting for years. I offered $500 for all three, but think that may be too high. Any ideas?
