Great to see you are happy with the upgrade. so i am guessing you think it is worth the investment?
ColorDMD are worth the investment in all cases. Pinsound - In this case, the original soundboard is unrepairable (economically), so it was a great option. The original sounds are used, but sound is vastly improved through the pinsound board as there are limitless settings and better speakers. The real value in pinsound is with the community created sound packages. They add sounds and music that change the entire sound system. Gunners and Star Wars are two examples where pinsound is almost made mandatory.
