Buy the TE410P that can be converted or upgraded to a TE411P for $100 less
than if you just purchased the TE411P straight up.  Test it as a TE410P and
if you dont have echo or can eliminate it then good, you make out well.  If
not you upgrade.

The E400P offloads most of its work to the system from what I understand so
you will use alot more system resources.  You also have no upgrade path.  If
you are lucky, you can use the E400P card if you have a beefy system already
that can handle it and you never need hardware echo cancellation, but thats
a gamble.
