If OP doesn't need high volume processing I'd suggest a slosher-type tray insert. Depending on the size of the tray you could do up to 4-6 sheets at a time. Takes more chemistry though. But - no scratches, no handling of film. And you can do intermittent or reduced agitation (which doesn't really happen with shuffling). A slosher is easy and cheap to make.

Don't get me wrong I'm not knocking shuffling. Just throwing another option out there.
