Bill, I voted for the Festool, in my honest opinion, the $90 difference between the Festool and the EZ with a good new saw, is not very much, over the rest of your lifetime
I have to again say that I think the real ace in the hole is the Festool saw itself.
I guess you could try to have the best of both worlds and get the Festool saw, and then the plate to fit the EZ rail system???
I do not know much about the EZ system, it looks good, but like I said, for me the real heart of the whole guided rail system, is the saw, and beating the Festool TS-55 is not easy thing.
Good luck with it!
