I think the MXB1002 is the lowest
cost Behr mixer with anything like two direct outs.

By direct outs, are you referring to a tap on the preamp before signal
runs through the rest of the mixer? If yes, I assume you suggest this
to minimize extra noise introduced by the mixer circuitry. How
significant is the additional noise not to want to use the main outs?
I can get away with a UB1002 ($60), but sounds like it has no direct
outs.

I'm more worried about the sound quality of the Behr's preamps... Behr
is cheap, and I can always use the functionality, but my gut tells me
the sound of a dedicated pre (DMMP3) is going to be noticeably
superior. Do any of the small Behr have guitar imp. level inputs?
