I wouldn't go over $15 including the shipping for a saw I'd never seen.
And $10 without shipping will buy you a good old Disston, or Atkins, or
Simonds, etc. if you're willing to invest some time going to estate sales.

OTOH, it might be worth the $12.58 (current bid plus shipping) just to
cut it up and make scrapers.

Just a thought.
