Looking for a bigger submersible pump

[FishGuy5]

I need to replace my Mag 36-way too loud! The pump has to be submersible. It is my return for my 180. Anyone have one they want to sell? Or any recommendations and where to get it? I don't think I have the room for an external, so please no recommendations for that.
Any help would be great!
