I am just getting my SuckIt up but have not used it to any extent. Not being too concerned about static discharge, I ordered a long Rockler hose which I had to cut down. If you have a number of shop tools, you probably already have some kind of vacuum exhaust system, ShopVac, Harbor Freight, or other.
The simplest (cheapest) systems like mine use plastic tubes and blast gates to connect the tools, one at a time, to the ShopVac or other vacuum. The tube/blast gate kit I purchased included a length of "wire" which was to be wrapped around the plastic tubes and grounded. I didn't use it. I suppose that if you haven't already blown yourself up in a dust explosion, you might say you don't really need grounding. If I had a business or really moved some sawdust, I think I would install a metal tube system.
Grounding aside, I found that the Rockler hose closely fit the SuckIt base hole but not closely enough. That is, it was loose enough that I was afraid that it would either fall through or fall out during carving. Adding to this was that there wasn't any support for the hose. So, this blog was timely as I am working on these issues.
I am addressing the "hose fit" issue by making a "custom" 3D printed hose adapter. I've made a number of such adapters because it seems like every tool in my shop needs a different adapter. I am adding an "adapter ring" feature that will prevent the hose from either going deeper into the shoe or coming out.
The hose support issue is another story, but I will probably start with the Inventables' solution. I made a fold up table, similar to the Carmichael design for my X-Carve, but never really fold it up.
The good news is that Inventables continues to address problems and provide solutions like the X-Controller upgrade. I would like to second several comments about "what is really provided/can be ordered separately". For example, when I upgraded to the X-Controller, I purchased the "side board" which I never used because my X-controller is mounted underneath my table, a combination of not understanding and drinking while ordering!
As a final comment, I would like to note that Inventables is a business, not a charity. So, you have to expect some "markup" for them to survive and continue to invest in improvements. One of the worst things that can happen is that a company goes out of business and you can't get replacement parts. As far as their prices being "twice" the price of the SuckIt, think about purchasing/making the extra parts for the SuckIt that are being provided by Inventables. You're still going to need a hose and a support.
