BUBBLE MAGUS 220. HELP

[Trocar70]

Hi everyone. I came home today to find my protein skimmer making a loud noise. Turns out my impeller on pump has broke into a million pieces. It's the EHEIM pump. Now I have looked online and the replacement piece is or seems to be very pricey. At 149.00 dollars plus shipping. Would anyone know where I could possibly get this cheaper. Any help would be great. As I can't go long with out it. Oh and I'm from Alberta.

thanks.
