I have installed over 150 of them, and specified about 20 of that number myself. I think they are great LV transformers.
Pros
1. When installed correctly, they produce little or no audible noise
2. thru the latest design batches, they are easy to wire
3. some come with a voltage tap range from 11 to 15 volts to handle all sorts of voltage drop issies.
4. Can be oredered with different number of load side breakers.
Cons
1. Expensive, depending upon your needs
2. Take up more space than the equivelant load size plate transformer.
3. Certain dimmers cause them to hum, solution to use LV dimmers or dimmers with neutrals [typical of all sorts of other transformers]
www.q-tran.com As far as cost goes, they can get very pricey, depends on what type ordered, VA, # loads etc. Most consumers don't know enough to care when cost comes into play, so they may be a hard sell to a budget wary individual.
As long as they are not stolen, I would consider it.
Oops on the web address, sad thing is I know the owner of the company to.
