Wayback machine is free, the internet archive, but as I think about it, if it was a pay-for-it Handango thing, it wouldn't be at the archive.
Best way to get something like that is to write the author but also try posting around like you've done, seeing if anyone has a copy, since handango took it off their site.
If they took it off, that might also mean it had bugs they didn't want to fix...I don't know.
