Did you read any of my posts? I'm not brand loyal, and I love the 7900's. It sounds like you're the one who is brand loyal.
Look every manufacture has problems, it's just how they deal with them that matters. Dolmar doesn't communicate well with it's dealers, and that is part of the problem. One dealer knows this or that, and the other dealer doesn't know anything at all.
Don't forget some people on this site have a vested interest in one brand or another, and they make their living selling that brand. Just because someone points out a potential problem with one model, doesn't make this thread out of control.
