Good comment Tom,

We really should all try to help each other more.
I have been testing some new hardware & will try to post it today.

Also, Tom, what about adding an optional field for price, just so people
can have an indication of cost involved?
I know that soon goes out of date & currencies don't convert easily it
can be helpful (although what you pay in Dollars, we then pay in Pounds

For example the Echo Cancelling card from Phoenix (see

Clear One unit, and yet there are places where I have run one as a

BTW Doug,
This card is more than adequate for a desktop node and allows you to use

By the way, both of the mentioned devices are included in the hardware
reference on accessgrid.org:


You might find other hardware of interest there, too.

If you're using hardware not listed in the hardware reference, or have
comments about hardware already listed, don't hesitate to post them to
the site.  It all contributes to the value of the hardware reference,
making it easier for users to make decisions when building a node.
