My Delta 66 won't fit in my new Mac (surprise, surprise). I'm looking for a solution to run in between the Mac and a Mackie. At the moment, it's just for basic but quality clear sounding VO work. I'm guessing that FW may be the way to go. $200 would be an easy cap, but if there's somethinkg killer for 300 with room to grow, I'm all for it.
