I have had very good luck with a Tascam US428. New ones are out there for $400 and, speaking as the former owner and user of a Red Rover, the US428 is a BIG step up. Eight faders in banks, EQ, pan, and lots of routing. I use mine for a controller - plus, an SPDIF digital stereo out from my mixer goes into channels C&D of the 428 for playback controllable independently from my headphones, headphone amp & monitors. I don't record through it, but when I was having trouble with my soundcard I did so without problems (only recorded 1 track at a time, though). Like everyone else, I am always upgrading, but this one does the job.
