One of the benefits of that SM10 is that it seems to be almost exactly the size of two Digis!
I personally use a really old 16 channel Mackie CR1604, which has 6 (plus one hidden) aux channels. I don’t need them all, but it’s pretty flexible. I picked it up used locally for very little money. It’s been useful, but it’s kind of large. It actually has its own table in the corner.
