Nice review Ryan. For your sized shop with multiple tools I see something like this as the best dust solution going. With a lot more room, I'm still on the fence. My use of several smaller machines (also lower cost) and hardly any ductwork (direct connect) I am getting rid of what I need to, and not spending all of my wood buying $$$$ on DC. 

Plus with my lungs even with a super high end system I still wear a respirator, just to keep ANY of it from getting into me. Or at least as little as I can manage. 

I think the number one thing someone can do with a shop is have natural light coming in, either doors or windows, so you can get a good look at all of the airborne fines. I've been in a number of shops where a guy with thousands in DC equipment, gets done cutting, sanding, whatever, and switches it off. As soon as they turn it off, also off comes the mask. Meanwhile the air around them is still full of floating fines, and there they are standing in the midst of it with nothing on to protect them.
