I'm currently using a PreSonus Firestudio Mobile on a PC. If you're on a PC, you'll need to have a compatible Firewire Card to go along with your PreSonus device. You'll get great audio, but you have to futz with it a bit to get it to work properly with Band in a Box. When Band in a Box and the PreSonus Universal Controller are loaded, they can get into an argument over which settings your Audiobox should have.
FWIW, It's definitely worth upgrading to Firewire instead of USB. You get a multitude of analog ins, 3 pair of DAW ins, a S/PDIF stereo in and 3 pair of audio outs on a Firestudio Mobile. Your Audiobox will provide even more. It's also possible to daisy chain PreSonus devices together through Firewire so you can easily grow your possibilities do live recordings with a multitude of direct to digital audio.
When you're ready to transfer your Band in a Box tracks into a DAW, the included Studio One Artist Two is phenomenal.
