You want me to get the SAZ-3500 to put it up against the RF 2500? I didn't test my RF 2500's to put it up against anything else. I tested it because I wanted to know for myself what it actually put out. I'm a skeptic when it comes to Birth Sheets also, but I saw the proof, and I'm happy with it. Ive heard nothing but good things about Sundown and will be getting one or installing them for my next customer. When I get one I will gladly test it. But like i said, i'm not doing testing to put any brand down. I think most people knew that. Some people have boners for a specific brand. Nothing wrong with that, just like there is nothing wrong with seeing value in other brands too. I like the test and I am sure Sundown would be right there too. We are lucky to have so many quality choices. +1
