The Key Largo looks rather nice, it is quiet expensive though. Iāll have a look at rackmount options, I have a half-rack planned, so maybe I can find something that fits in that format.
The Mackie 1202 without the 4 mono channels would be perfect, and so much smaller than it is now. Maybe one can mod it? 
Regarding rackmount, this looks quiet OK, just 1 FX send though, but still rather nice. Might be a good option since it can sit in a rack and not be on my desk. Does mean slightly less quick/easy access to volume control of course http://www.alesis.com/products/view/multimix-8-line
Yeah, itās totally understandable from a market perspective 
Audio interfaces with live monitoring could also be an option, though FX sends (and pan) will probably be missing. I was unpleasantly surprised by my NI Komplete 6, which has 4 input channels with ālive monitoringā but that actually only works for the first two channels 
K-Mix seems to be the best option thus far, but Iām not sure if Iāll like it, since I switched to hardware for more hands-on/tactile control and Iām not sure if the K-Mix will work well for that.
I did find this one, itās digital though and relatively old (±10 years), so not sure how easy itāll be to find one and how well it works https://www.roland.com/us/products/m-16dx/
