Point me toward a no frills beginner flexshaft

The one I really want is the evo micromotor but it’s $1800 and just not realistic rn.

What simple foot pedal flexshaft would you go with to get a few years out of before you upgraded?

I would love to spend around $300 but if I have to go to $500 that will actually work I will.

I am Generally a buy it for life kind of person so buying a cheaper version of something is really outside my comfort zone. But I’m needing to make compromises to get my bench useable.
