DC is different.
For cheap motors, old treadmills seem to be the way to go, combined with a KBIC speed controller.

Unless you really are trying to do the conversion as cheap as possible, I wouldn't use anything other than a KBIC, as they're quite popular, reliable, and not that expensive to buy new. I run a KBIC in my little lathe, as it came with a DC set-up and a dead Cheetah drive, and a KBIC was the cheapest main stream option I could find at the time.

I've still got the 600W DC motor and associated electrics from my Warco WM 16 if you're interested?

Here's a couple of pictures and a video of the motor running. Note that when increasing the speed, the motor "kicks" in about 2 or 3 spots through the speed range. It doesn't do it when reducing the speed. Not really sure why it does that but it's always been the same from brand new. I'm guessing it's a characteristic of the Chinese copies of the KB boards? It's never caused a problem as the motor runs smoothly if the pot is turned slightly past the "kick" point. Can anyone advise on this?
