I have a TS75 - the bigger version of the 55, along with an MFT, several sanders, a router, and the domino and a fein turbo vacuum. Most all purchased on the refurb closeouts.
I have previously had a full commercial grade table saws. I was doing high end installs, and the like when I was between jobs. I will say that the track saw does 80% of what a table saw can do, and a table saw does 80% of what a track saw can do. There are some things that a track saw cant really do, and some things a table saw has issues with. They really compliment each other. If I had room for both I would have both, but in a small garage, a full size cabinet tablesaw is difficult to use with sheet goods. To do 8' cuts you need 18 or so linear feet, in a 20X20 shop, not really possible. For stuff like building speaker boxes and case work they are outstanding. I resisted getting the MFT for a long while, seemed really expensive for a table. I always struggled getting right angle cuts before I got it. With the MFT, it is just there accurate and square. The track saw is 70% part of the system, the MFT makes 20%, parallel guides 10%. Even if I had a full table saw, I would break down my sheet goods with the tracksaw, and there are some cuts the track saw is the only good option.
For breaking down sheet goods, I use a sheet of rigid foam under the piece I am cutting. It really aids in dust collection, not dustless, very minor cleanup.
So love mine.... but would still like a full tablesaw
