Most things come in copper only as an option, but I would get acetal (delrin) and nickle on anything new I buy. Cleaning copper is such a pain in the ass and the cost is basically the same.
I like full copper my self. yeah it is a pain to clean. Something rough to take off oxidization helps, fine sand paper for base plates. I forgot what my father told me to clean the internals with a while a back I thought it was a write brush wheel maybe or something. :-/
