Howdy,

More info:
I thought about the lack of bass but figured that it might not too much of an issue because of the type of music being recorded. He is mostly mixing folk consisting of an acoustic guitar and a female singer. If he was doing drum and bass then that would be another story.

I suppose the other thing to keep in mind is that this is more of a hobby for him. It isn't of paramount importance for him to have the very best gear. He just wants something half-way decent. The Behringer's seem like they could do the trick. It sounds like there is more support for those than for the M2/M3's.
