You just makin' it up as you go?
The Festool saw is $615, comes with a 1400mm track, and a SYS-4 systainer, it's not possible to buy the saw w/o the track and systainer.
1400mm/55" tracks are $125, the 1900mm/75" tracks are $195. You can also substitute Makita tracks for a few bucks less, but the difference isn't significant.
I got my TS55 REQ for $464 during their reconditioned sale. Comes w/ a new splinter guard (which isn't available on the Grizzly saw) and a brand track. Condition was excellent, barely used. 1 year warranty vs 3 year when purchased new, but hey, it was $150 cheaper.
They were doing 40% off late last year too, which would've dropped it to $369. Same deal, new track, new splinter guard, but that's apparently never going to happen again though if you're to believe what they say at Festool corporate.
The Grizzly saw is $260 bare, $60 for rails, figure out your own storage.
Not saying the Grizzly saw isn't a good deal because it is, especially when you can't catch the Festool saws (you have to be on top of their site when they're running the sale b/c they go quickly), but get your facts straight, eh?
