Im looking for the best option to power a small lathe. (ML10)

The standard motor is a 1/2hp 180v Dc motor but Ive killed the controller and a replacement is about £115. It looks like I could have issues with the 0-10v speed control and need an isolated supply etc.

I would like to do threading so wonder if I should swap it out for an 1.5hp AC motor and VFD to give plenty of power and easier connection to the BOB.

Any pro's for sticking with the original DC or swap it out? thanks in advance
