Greetings,
I have to agree with Ray. Upgradeitis is an incidious disease, and struck me after I had received my VP100 and QS4's. They quickly became VP150 and QS8 and I have never looked back. I think part of the problem is that when you buy from an on line only company, it is very difficult to compare models. If you are the type that would wonder "what if"...go for the best the first time around. It's cheaper in the long run. BTW, my room is 15x22x8, and the QS8's are outstanding...
