I just picked up a used Alesis Multimix 8 line rackmount mixer at Guitar Center to $29. I've read that some of them have a hum but this one seems quiet. It does have the tip of a trs connector broken off in the right channel of one of the channels but since I intend to use it for mostly mono inputs to extend my console at times, that's not a big problem.
As far as Ashly gear, I've heard nothing but good things about them. I have an old Ashly compressor that is my favorite.
