I've been using a Kata Koala bag that I purchased used from the Yard Sale on this board. Before that, I had been using a Portabrace mixer bag setup, which was quite nice, but I like the look, feel, and layout of the Kata bag as much if not more than the PB.
I don't know how it compares to the one you linked to, but if it's anything like the Koala, you'll love it I'm sure.
