I use it and I really like it. It's got a ton of inputs, a coupe of mic pre's if you need them and it is pretty easy to use.
For the digital inputs I use an Alesis AI-3. That plus the 8 analog and the two mic inputs gives me 18 inputs all in a nice neat package.
I use it with Cubase and a laptop. I wired it, the AI-3 and a patchbay in to a 3 space rack so I never have to go behind the unit.
It only goes up to 96khz...not getting into that argument.
I'm sure there are better AD converters out there and there are definitely better mic pre's in the market. But this things got everyone beat in the ins/outs department.
The first ones on the market has some screen problems but other than that there haven't been any wide spread problems with the mkII that I am aware of. There's the occasional noise complaint here and there, but it usually ends up being something else.
I love mine and I recommend it.
