Bubble King 180 replacement pump. Bloody expensive.. Solutions?

[One_Divided]

So my motor block and impeller are toast. I have swapped components with a freinds' working pump and I can confirm that it is both parts.

The pricing I'm getting back on replacing the pump is atrocious. I may as well buy a brand new Vertex Omega for around the same price..

Has anyone found a cheaper solution for replacing this pump? Perhaps modified their skimmer to make it work.. I love my BK180! Would like to find a solution rather than turfing some perfectly good acrylic. Thx,
