May I suggest something?

These things are designed to be easily rebuildable. I suggest you look into that first. Most likely, the springs and the brushes just need replacement.

There are tons of videos on Youtube as to how to do this. The problem you will have is buying the kit/parts for the rebuild.

Save your money and buy the MBShop members a keg.
