Power Supply to ODrive with Two D6374 Motors

I am looking to connect two D6374 Motors to the ODrive V3.6 56V controller. I was wondering if anybody had any suggestions for a good power supply for this setup. I am looking for torque control of the motors and a budget of $100 or less but will exceed the budget if the power supply is worth it. Let me know if anybody has any suggestions!

Hi

How fast do you need them to turn?

Cheers

More importantly than fast, how much power do you want at the motor side?
