I use the PC MAG with my EZ setup and am very happy with the dust collection. I can do a lot of cutting and have very little mess to clean up after I finish. I've found that the PC is a comfortable saw to use and has plenty of power for my needs.
I have the Porter Cable hose that adapts my HEPA filter equipped Shop Vac's 2 - 1/2" hose to my PC MAG dust hose connection. Eurekazone has a dust shield that they include with their system that you mount on your saw for additional dust collection efficiency. It works great.
My shop area is similar to yours and all has to be portable enough for me to pull my van inside during bad weather. For me the EZ has been a huge help in that regard, and it lets me cut wood without the need for a lot of shop cleanup after I'm done.
