I stumbled upon a site where SOMEBODY reviews MANY saxophones from a repairman's/engineer's point of view as well as from an aesthetic point of view. He talks about differences between different models as well as about changes within a model line over the years, regarding post placement, key supports, pivot screws, blue steel springs, stainless springs ... he seems to know saxophones inside and out. But, I can't remember how to get there or who he was. If someone has a strong suspicion of who/what I'm talking about, would you be so kind as to steer me in the direction? I promise I will write it down and never bother anybody about it again.
