Is there a special circle of hell where crappy power tools can be
consigned?

Freecycle

I run a freecycle group, and I suspect even they would turn their
noses up at my crappy B&D.

Time I had another clear-out though. The "freebie" mitre saw table
needs to go amongst other things (it's god awful beyond belief) -
maybe I can palm off the b&d as a free extra.
