If you went out and bought the parts to build the Diamond double platter ball polisher yourself, you'd already have about $400 invested in parts alone...then still have to build it. Unlike other ball polishers, the Diamond ball polisher is built to last forever, and it does, i would know, i designed it way back in 1995 and have never had one replaced because it wore out. Hard times in Sacramento, CA has had one of the first ones i built 22 years ago. Diamond has a distribution center in Finland, check with them to see what your cost would be through them. AND....the sprockets that separate the balls are specifically to fit snooker, billiards, and pool balls with no gap between the sprocket and the balls, ALL other polishers are not capable of sizing the balls, which really makes a difference in the outcome of the finished cleaning/polishing of the balls.
