Vortech advice?

[aqua_techy]

Hi everyone,

After 9 years of long service, my two EcoTech MP40ESw pumps are in need of some TLC or retirement, and thought I would seek advice from the community here! Current tank setup is 100g FOWLR + LPS + Softies; Radion XR30w Gen 2 lighting, Neptune Apex controlled, ATO.

Context: the wet ends are toast, magnets rusted through and warped.
Unit 1: has functioning EcoSmart Controller + drive motor + power supply.
Unit 2: not functioning, controller's control knob not lighting up, drive motor not spinning up. Uncertain if controller, motor, or both are toast. Power supply tested and functional.

Option 1: I can easily resurrect Unit 1 with QD driver and new QD wet-end, but Unit 2 will take more work and I need to figure out what's wrong with it. Any advice in diagnosing this? Or should I just send to EcoTech?

Option 2: Resurrect unit 1, scrap unit 2

Option 3: Scrap both, put the money towards a new wavemaker. If you think this is a good option, what would you recommend?
