I have not cut any Dibond at all, but have used my Festool to cut aluminum and Plexiglass, as well as plywood and some hardwoods, with no issues at all. The saw, combined with my Midi, makes for a nearly dust-free experience and nice cuts. I disagree that a tablesaw is a must have. Plenty of fine woodworkers get by without one and other options, such as a router table, CMS or bandsaw. Using a track saw to cut down sheets of Plexi or Dibond seems to make sense to me. Cool thing is, you can buy one, test it out, and if it doesn't do what you need, you can return it.
