Guys I know swear by SS media. They use magnets as well but put a towel or something to cover the magnet. Yank it off and media drops right in a container. Downside is I have a vibrating cleaner. SS media needs to be tumbled as I understand it. Want to go that way but looking for large, reliable, and inexpensive tumbler. It's fast as well.
They have 'em, just not the inexpensive part.
