Robert, as you're thinking about it, keep in mind that the Roland has a bigger speaker and more I/O options and is considerably less than the Mackie. No shot at Mackie, as I own an 808s and two i300 speakers; it's all great stuff.

Though I haven't used my CM-30's as monitors yet, that's what I really bought them for. When we put them on mic stands and had them next to us (guitarist and me) we could hear the mix pretty well without any type of monitor. It was our semi-deaf sax man that stands in the middle who needed a monitor to hear the mix.
