Warrenty and lifespan of cd players

I am wondering why it is that so many people here, there, and everywhere, seem to upgrade to expensive players when many such players seem to enjoy a very short lifespan relative to other components and have such poor warrentys. I am not being critical, but rather I am curious. I would love to own some of the cd players I have seen and read about, and I am more than willing to save for such a purchase because I do believe the source is very important to a system. But then practical considerations raise up like a red flag and I am discouraged. I guess what I am asking for is a deeper understanding, perhaps some debate that might provide some overview. any coments on this subject would be helpful
