Calling on the Movie Braintrust

A coworker of MAB's is looking for a copy of the 1980 TV movie Gideon's Trumpet. It is available for gobs of money on Amazon (I think it starts at ~$45), and he wants to know if he can find it cheaper anywhere. I know a bunch of you are movie buffs; I hope one of you can point me/him/us in the right direction.
