Thank you guys for your answers. I think I'm going to try these servos, with analog drivers to close the loop on LinuxCNC.
James, here in my country, Argentina, there are suppliers that sell yaskawa motors, but the price is four times the price for a chinese driver, and the connectors and cables are not included. I'm going to check out on ebay to see if there are some good priced yaskawa servo motors, but I don't think any other servo motor can be cheaper as the chinese.
