The only real way to find out is to open it up and look. There's no point in guessing.

The symptoms of PCB failure are that the fan doesn't turn off so the battery needs to be disconnected to stop it! That's clearly not the case with your car. Edit: Please see information from Mike Noc in post no. 10.
A new Revotec is expensive and requires wiring modifications. You said that you wanted "a budget fix" and that is new brushes on your existing motor or a gold resistor depending upon which type you have.

You're assuming that your existing system is irreparable but you don't know that! It's better to fix what you've got if that's possible.
  1. Look through the radiator grille at the fan blades housing. Can you see a rectangular silver resistor at about the two o'clock position? Edit: See photo no. 3 in the next post by Arctic.
  2. If yes, you probably need to replace it with a gold version. This is a very cheap repair.
  3. If no you probably have a 3 speed system needing some new motor brushes. You said that you are not averse to this repair job.

So please report back Peter with which fan you have and we'll take it from there.
