I'm looking at picking up a USB interface for my iMac and MBA. I will be using it with Logic 9 and Presonus Studio One 2. I looked at the Duet 2 but it doesn't have the IO I am looking for. I don't really want to go up to something as pricey as the RME babyface, so that left me leaning towards the MBox 3. I have read that the drivers can be touchy outside of ProTools so I'm looking for feedback from those of you who have used it. I had also considered the Focusrite Scarlet 18i6, but have really heard bad things about it's drivers. Any feedback or other suggestions?
