I am going to probably get the Roland Octa-capture OCTA-CAPTURE - Hi-Speed USB 2.0 Audio Interface, which is USB-based, is more feature-rich, and gets positive feedback for reliability and performance both on Amazon and in online support forums.

It works great out of the box with zero hassle and has a lot of nice features the FireStudio doesn't have - of course for almost twice the price it better have some extra features!

I still think it has great features and would have kept it if it worked for me.
