I'm taking a good look at the Focusrite Scarlett 2i2 because I don't need that many inputs/outputs but I heard the Saffire 6 is now USB 2.0. I just need a small cheap interface and I'm getting rid of my Mbox 2 Mini. Basically I would use this just for recording my vocals. I may be using the preamp as well until I buy a better one. Which is the better deal? Is the Saffire worth the extra $50? I'm using a Blue Bluebird microphone running Pro Tools 10 HD on a Windows 7 64bit btw if that matters.
