Note:  If you wish to pay money for access to Ecco, rather then rely on free resources, you can do so by following this link to a website provided by http://eccopro.com/.  This link also provides access to a conduit by which Ecco can be synchronized with Android (also a paid service).  Paid services can be very useful for those who are not able or willing to invest the time to follow the free instructions available at various locations, or for those who want the Android conduit, which is available only through Compusol.
