Hi there,
I would select somrething like this
Tascam US2000 USB 2.0 Audio Interface PreSonus FireStudio Project FireWire Interface Lexicon Ionix FW810S FireWire Recording Audio Interface Echo AudioFire 12 FireWire Audio Interface
It depends now on what you want to record and what is your recording setup.
My preferences are Tascam and echno audiofire.
Cheerz!!
