[RE-wrenches] Defective modules-American crap?

Our only protection at this point is the Wrenches list.  If anybody on 
the list is seeing premature failures, we need to know.  You folks have 
saved my tushy many times in the past.  For now, I've stuck mostly with 
Solar World, and not had problems.  I will not be afraid to call any 
module manu out if I have to, to help save this industry.  If the 
failure rate is high enough, and energy production effected enough, I 
could see Congress even pulling the 30% tax credit.
Tying warranties to nondisclosure agreements is bordering on unethical.
I always knew something was fishy with modules selling for under $1/ watt
