saw a guy with a Mackie U420 Firewire 4 Channel Mixer, with a Stereo Aux Out, but it only had 1.

Without having to buy 2 of this same mixer, can someone help me find a mixer with at least 2 Stereo Aux Outs?

i think a lot of the aux outs are in mono on a lot of machines. I know the sp 808 has a stereo out and aux in but i never used it for send/return.
Look into behringer mixers, i got one but i think the aux out are in mono.

probably gonna have to look at the larger size mackie/yamaha/etc mixers (12ch+)

even then, most of the time auxs are mono send with stereo return
