How do rotaries get balanced?

I heard a couple guys stating that they had their "rotating assemblies"" balanced, how does that work out? what exactly isdone to them and cost?

IIRC the rotor weights are matched (they're already very close from the factory), and the e-shaft is balanced just like any other crankshaft... not sure how that actually works...

I wouldnt worry about balancing unless you plan on serious power mods. Even some guys that drag race dont balance there rotors for various reasons. I dont know for sure either what the process is or price but uness your ready for a rebuild/ port job I wouldnt be thinking too much about it.
