Thanks for your excellent and detailed post. As a retired designer and 
specifier of sound systems for public buildings, I appreciate your 
struggle with the process.  I regularly ran into similar "do it cheaper" 
contractors bidding for the systems I designed.

  I'm sure you're aware of the issues with the use of switching power 
supplies for low-voltage lighting fixtures. Here in northern California, 
there were many of them in the home I bought here, and I've not been 
able to find replacements that are not noisy, and a transformer won't 
fit in the backbox.  Electrical supply stores sell nothing but un-labled 
"electronic transformers."  Can you offer any advice in this area?
