Yeah, it's a fun little side collection. My 5 year old son will receive Darth Vader in a few months.
He knows he's not supposed to play with it, but I wonder how long he'll be able to resist.
As far as cleaning them, they are very high up on bookshelves, so not exposed to dust too much. Our cleaning lady can't reach that high anyway, so I'll be dusting them off from time to time.
