I was looking at that or maybe an Xrack. Another alternative I was considering is the QU-Pac.
I went with the QU Pac as my second mixer as I already owned and still own the QU16. This means I can share scenes and shows between the 2 mixers in seconds, I could slot either into place quickly if the other failed at a show, the learning curve was very easy as I already knew the QU16 inside and out and if I do need 32 channels, along with my D- snake ( which I can use with either mixer), I have them using the QU Pac.
Lastly, I like the fact I can still mix from the QU Pac if wifi goes down.
I was tempted to go for one of the other rack options but paid little more and got much more benefit for my purposes. The SB wasn't out then but I still like having a screen on the QU Pac.
