I don't want to get into a flame war, but I'm curious what product you purchased was the biggest disappointment. In other words had the greatest gap between what you expected and what it delivered.
Mine would have to be the Pioneer SX-9000 Receiver. It looked beautiful but had so much background noise that I could only listen to it for a few minutes. And, the built-in reverb was nothing more than a spring encased in a metal enclosure. I had my Tech go through it to try to eliminate the problems but there was nothing even he could no. It just wasn't that good.
