WTB Skimmer Pump and or Pump Parts

[saltwater-virgin]

Have a Euro Reef RS 180 with a Gen-x 4100 pump. The impeller magnet is busted on the pump.

Looking for a replacement impeller (I believe the Sedra 5000 needle wheel will fit). I'd also consider buying a new pump. I don't want to pay the $80 + shipping for the Reef Dynamics replacement impeller.

Would I be able to find this in Edmonton?

Alternatively someone can have the skimmer body and pump with broken impeller for real cheap and I'll buy something new.
