HA! I thought I'd like to put my 2 cents worth in too, but I think I'm about broke after those other weight threads.
One thing is for sure, we don't all like the same thing. I think it is a personal preference issue. Get what you feel comfortable with. Just because someone else thinks it is better, does that mean it is better for everyone?
That being said, if I were buying another TV, I would prefer the dually. To me, a wider stance means more stability. Really, I don't care what everyone else wants, just as long as me and the bride are happy.
