Query: I can't imagine paying for this...

Well, mine was included with my 875. The clasp bent open the first time I picked it up. After dealing with that for a while, I just tied it on. So let's just say you'll probably want a shoulder strap, but use any old thing you've got lying around before paying real money for this. It must be embarrassing working for Ryobi.
