Was about to mention that, should be able to buy a set of brushes, a rectifier and a regulator. Weighs next to nothing, takes up barely any room. Even if you can't pull it apart yourself, a auto sparky could. About the only parts they ever replace in a rebuild. The rest is just a strip and clean charge.
Unless they're completely burning out the Stator????
Then it's usually a bin job from memory. Been a while since i stripped one.
