I recommend a control surface rather than an analog mixer because it's a lot more versatile. This is what I use:

I regularly mix songs with 50+ tracks and 16 faders is enough. You can just bank through or else scroll one track at a time if you need to.
Of course, if money was no object...I'd probably have this. Lol
