There is indeed a correlation between cost and quality, but it is not 
the only factor.  Is a Lincoln that costs more than a Lexus any better 
quality.  I believe it is not.  But is a Lexus that costs more than Yugo 
better quality.  Here I would guess that it is.  You need to look at who 
is selling or proposing a solution and how they are achieving the lower 
price.  The credibility of the messenger is paramount.  Which leads your 
next point...

Would you listen as intently to a person of unknown repute when they 
tell you that you can wire your starter using 28 gauge wire because the 
starter's average current consumption is minuscule.  They are right in 
their statement.  If you average the current consumed by the starter 
during a 1 hour flight, you would find it to be well under 1 amp.  What 
this revolutionary is missing is that wire gauge needs to be based on  
instantaneous current not average current.  So much of the revolutionary 
leading edge technology is based on similar analysis.  The designs are 
often done by individuals that lack the big picture and insight into the 
real working environment of the products.  

Look at the credibility of the source and the reasonableness of the 
arguments and then make a decision.  And remember the golden principle: 
 If it sounds too good to be true, it most probably is.
