asterisk users - Apr 2007 - Purchasing a Sangoma A102 - should I get the hw echo cancellation or not?

Shortly, I'll be purchasing a Sangoma A102.  I'm wondering if I should
spring for the hardware echo cancellation circuit or not.  Upon
initial implementation, the 2 T1 Ports will be used as a passthrough
as we slowly transition off of a legacy PBX.  Eventually, we'll only
be using one of the ports, and will be providing VoIP service to a
bunch of SIP deskphones.

So - with that usage scenario in mind, is it worth the extra $800 for
the echo cancellation?

As a sidenote, I assume these cards are PRI-compatible, correct?

Thanks!

We have installed two of the Sangoma 2 port cards.  Both had echo 
cancellation.  The cost add on was about $450, not $800.  I also had 
a single port T1 card without the echo cancellation.

The extra money is worth it to me.  Less CPU load and it just plain 
works.  And if a customer is willing to spring for a PRI, they 
usually won't complain about the extra cost for better sound quality.

Yes, they support PRIs.
