Bally are easier (at least to me)!

Point being, that there are MANY supposedly "good deals" on older computerized slots, but they are impossible to fix! Your options: try to find a replacemend board for your particular machine, try to find a repairman who actually knows your model, or throw the machine away. Ballys are actually fixable by curious people that enjoy tinkering...

Now, I realize that for many people, that Ballys are too much to grasp. Let me put it another way - if you can work on old juke boxes, or old pinball machines, an Electromechanical Bally will be easy for you to fix!
