I've had really good luck with the echocan preload patch that was posted 
on the asterisk dev list a while back as well, and I've been 
recommending it to people as well.  This has really helped minimize the 
echo problems to a minimal level, although I don't know about 
recommending this system to our customers.  I still think a lot of my 
audio quality problems are being caused by my phones (not echo, but 
clicks and pops and various overmodulation problems).  We're getting 
there, but I'm still nervous with trying to sell an * system to someone 
who is used to the quality of a traditional PBX or key system.
