Why not just buy your materials from a reliable plumbing supply place
that will rent you the tool for a day. Put everything in place, and
then get the tool and assemble the connectors in a few hours.

You can also rent the crimp tool from Home Depot, at least one that has
a rental department. It's cheap for a few hours, even a few days will
cost you less than a new tool.
