My mixer needs is a minimum of 4 mic inputs (xlr) more is always nice for room to grow. I've found a few, and even the yamaha one you were referring to. I really like Behringer brand mixers, I have a small one and used many of them in the past, and have really liked what I got from them.
As far as monitoring needs I am puzzled haha. The more I have thought of it though the more I have been considering powered vs unpowered pa cabs, and I think I would like to stick with powered
