What about the Behringer XR-18?
Packs a lot of bang for the buck.
I didn't realize those could be used as a DAW interface. Cool units for sure, and they had a used one recently at the GC near me. I assumed it was only for live so you could walk around a venue with an iPad to do the mixing, and not be tethered to a physical board. Still, the $250 price tag of the UMC1820 makes me think I'll probably show up at GC one day with a couple of things I don't need any longer, and get one for more like $100 after trade-in.
That said, my pair of ancient M-Audio Delta 2496 cards ain't really broke, and both Windows and Linux are totally happy with them. The primary reason I am toying with the idea of getting a multi-mic interface is that I started recording acoustic drums recently using both of the M-Audio cards at once. They are sync'd over S/PDIF, but I have found that the start times for recording are not sample accurate, and even though they are using the same clock, with no drift there, the moment they start recording is not identical, and I end up having to slide two of the four tracks of drums around due to phasing that kills the punch. Now that I have identified why my four channel recordings have varying amounts of offset, I spot check and correct every time right after recording, but it's a step I would like to eventually eliminate.
