I have a Behringer XR18r and for the money, you can't beat them for small(ish) band needs. You need a tablet or laptop and a separate router is recommended, you get 18 channels, 6 aux sends, some effects and can save configs.
if you go old school analog, I think a new/used Yamaha would be a real safe bet. They're nice, sound good and can be had new/used at a decent price w/ aux send(s), basic effects, compression on a few channels.
I have a MG12X I bought used a number of years ago, or maybe the 16 for you? I dislike how they all count channels these days. The 12 is really 8 because they count stereo inputs as two channel. The MX12 has 8 channel faders, so IMO it's an 8 channel mixer. All manufacturers are doing that.
