SSL certificates are free.  You just have to have enough knowledge to
distribute your own CA certificate.  For a VPN appliance, this should
not be a problem at all, since only your trusted users should be
accessing it. Even if you aren't competent enough to figure out how to
distribute your own CA certificate, I believe there are such things as
wildcard certificates.
