The LittleMachineShop HiTorque 6450 Mini Mill is the best in its class. It has the most power, the most torque, the most features and upgrades, and the largest table in its class.

Hi, hope there's room for yet another SX2 CNC conversion thread. I bought the LMS Hi Torque 3900 mini mill over a year ago and am very happy with the machine.

As I understand, all the machines listed above have some electronic control circuit which maintains RPM under various load.
