Any Festool saw should ride on it, whether you go with a proper TSC (technically a 2x18V) or an HKC (only 18V). Beyond that, your rails will be good for the Makita track saw (2x18V), Makita 9 1/4" saw (2x18V), Mafell Track saw (they have a second groove that will work on the Festool tracks, but their carpentry saws do not), Dewalt (same thing with the second groove), and likely some lesser known cheaper variants. Festool luckily kind of set the standard for tracks, so most will fit it.
