I love my NS7 because it’s bulky, heavy and um .. sexy? No, really, it just feels very sturdy, responsive and professional. Which makes me sometimes almost feel like a pro 🙂 It also works very well with any software, maybe except the one it ships with. And it really does look smug.
When the NS7 is too much mojo to carry around, I love the MixTrack Pro 2 for the highly portable usability.
