Hi,
did you not like Samp, or are you looking at a more convenient setup? I will agree that digi makes it real easy to get going with that MBox setup, but I wouldn't choose that over say, a Metric Halo Moblie IO + DSP and Samp, personally.
So many ways of working...in many ways it is a great time to be doing this kind of thing. Good luck with whatever you decide to use.
