Yes but it includes 30 days of support and 12 months of upgrades/updates :)

It really depends on your needs. They are both good systems. Slony-I is
a bit more of a beast to get up and running, and it is a batch
replication system that uses triggers. Once it is up and running it
works well though.
Mammoth Replicator is easy to setup and is integrated into PostgreSQL.
However replicator is 1000+ and doesn't support promoting of slaves
automatically (you can do it by hand) like Slony does. Replicator is
also live replication.
