asterisk users - Nov 2009 - Good quality replacement for Linksys SPA-3102 recommendation.

Can anybody recommend good quality replacement for Linksys SPA-3102 ATA?

I have to original Sipura 3K for over 4-years that are still working fine but
the Linksys 3102 I purchase are very poor quality (not to mention the echo on
PSTN line).
One unit quit working 2-weeks after arrival (needed to be replaced)
Second unit quit working all together after about a year.
