If you can read or measure the bearings, there are a number of sources, ranging frome realliy enexpensive to outragouis expensive and the price doesn't indicat anything about the quality. I just picked up bearings for a Saito 91, one bearing each from two sellers on Ebay and I couldn't be happier with the price and service. Ihad purchased from one of the other sources listed above and was not happy with the fit. I'm waithing to hear from them, so no names for now. My bearing set ended up costing under $8.00 delivered. Someone like Graingers will sell you a like set for about $30 a bearing. If you are ordering from Ebay, make sure that they list a manufactures name.
