I like the MOTU 2408MK3. I haven't used the analog 1/4" inputs for recording. Folks have said those are noisy. I have used the analog outputs and the digital I/O, all of which I thought were top notch. It's a bit of a beast though, you have a I/O card that goes into your PC or Mac desktop, then what looks like a FireWire cable -- but it isn't -- that goes to the unit itself. I like how it can be rack mounted, but that can be a pain if you don't have room for that or want that.
