Yeah, I've owned a few mixers and it's funny how an eight-channel mixer is not always so clear, especially cheating you on the number of available XLR inputs. I'd rather have a full pallet of options on the input side, including effects for each channel. Once each person's mic and instrument channels are dialed in, setup should be fairly quick. And I like the option of ALL channels having an insert jack to allow external recording. I also prefer analog mixers -- you look, grab and twist the knob. No messing around with different levels of digital screens.
If you stay with AC powered gear, I would strongly consider one of the rack based mixers that is run with a tablet Behringer XR18/Midas MR18 or similar. The benefit is you can walk out front with a wireless tablet to dial in the sound.
