Something to consider, the Festool will produce cabinet saw quality cuts. Do you need that or the accuracy of straight lines? If only the accuracy of straight lines Grizzly offers a track saw that might be the answer and take some sting out it being abused. But if you want top of the line and quality cuts I highly recommend the Festool.
Let me add a bit of buying strategy. If you are going to be ripping sheets of 4x8 plywood you are going to also need to purchase an extra length of track. The TS55 track saw comes with a 55" track, the TS75 track saw comes with a 75" track. To rip an 8' sheet you will need about 10' of track. The 75" and the 55" tracks give you almost 11', and you will need to buy 2 rail connectors, $36.
If you buy a TS55 track saw with 55" rail and add the connectors and a
75" rail you are going to pay $640 for the saw, $36 for the connectors and $200 for the 75" rail, total $875.If you buy a TS75 track saw with 75" rail and add the connectors and a
55" rail you are going to pay $750 for the saw, $36 for the connectors and $129 for the 55" rail, total $915.With the understanding that the TS55 needs an additional 75" rail and the TS75 needs and additional 55" rail the difference between the two saw set ups is only $40 more for the bigger TS 75 saw.
Just something to consider if you are thinking one saw over the other and will need to make 96" or longer cuts.
The case that comes with the saw is very good and easy to deal with, take the saw home with you. OTOH they could be abusing a $1500 TS.
Going a bit further, I recently had to replace my, all plastic, Stanley saw horses. The picture shows my set up for cutting sheet goods with my track saw and may be the only true example of something none of us thought was possible, having too many clamps. I ended up buying a set of Dewalt saw horses that have steel legs and pretty much plastic every where else. I think you can figure out the set up which worked well until one of the plastic legs on the saw horse buckled.
