Depending on your budget you can get some DMD pins in the $1800-2500 range. In the 2500-3000 range you might even start to find pins like Flintstones, Fish Tales and several others. They are out there.........very important for you is that you know how to repair these machines regardless of what you buy. Lots of working parts and alot of problems can arise as many of these machines are 30+ years old.
Good luck
