We used one at Recording Workshop several years ago. It was just all right. I didn't find the layout all that intuitive, and I think by today's standards, it's a little dated for a digital mixer. I'm unsure if it's compatible with non-Mackie production software.
A Tascam FW1082 or FW1882 in conjunction with a computer may be comparable, and I would suspect it'd (at least in the case of the latter) have better-sounding preamps.
