Donshoemaker,
For the weights, there is a guy here who sells MA-505-series main weights and sub weights (his store is a metal workshop). The main weight is JPY 9,000 (about US$90), and the subweight JPY 1,000 less (about $10 less). To me that is a fair bit (shipping would add a bit but not much) but 'parts arms' go for more, and I don't know what a machinist where you are would charge. There is another guy who does MS parts and I will try to get his name/site and post it here soon.
