Some days I miss mixing on a big analog board with all of the outboard toys. I used to mix differently back then, in some ways more active - for instance often making EQ changes on the fly throughout a song (especially vocals), rolling the HF in and out on a long reverb as an effect. I interacted with the mix more, whereas now in the digital world I don't really do this as much because it is slower to get around on. I just dial everything in and am mostly a fader jockey for the rest of the show. In the future if we ever have virtual reality console surfaces, mine's gonna have an individual knob/fader for every single function
Randy, your best bet for selling your old consoles is probably to studio guys. Lots of people in that world are still looking for nice analog desks like your APB. Check out sites like Gearslutz classifieds.
