I have a number of Digium T1 products (T100P, TE410P, TE405P and TE406P) as 
well as a few TDM400 based boards.  No failures in the last 2 years or so.

Not that I've seen.  I also have a number of Sangoma products.  Both work very 
well for me.  As an engineer, I can also see that the protection on the 
interfaces is comparable.

I don't think this is a Digium problem, at least not yet.  What did their 
customer service people say?  Can you ask for a failure report?  You note 
that power went out.  Generally when this occurs there is a very high chance 
of transient voltage spiking or line swells not only on the residential 
electrical power grid but also on the telephone network.  Do you have any 
telco line protection in place to protect the card from nasties coming in 
from the outside?  Is the protection correctly installed?  How about 
electrical protection?  The MOVs in your power strip and UPS are only good 
for a few hits before they become ineffective (something they never tell 
you).

Unless you know something more than you've presented here it is a little 
premature to start pointing fingers.
