Same saw, longer warranty, coupon book. Unless you get some sort of deal on the
saw, the warranty extension is not worth the extra money as if something is
going to go wrong, it will go wrong in the first year or so. However, I just
bought the "x" version of the 15 inch planer, and you get a choice of a mobile
base for the machine, a delta cordless drill, or a Porter Cable 690 router as a
free promotion. Same deal with the unisaw. I took the router, its a $140
item. I'd wait for a wood show if I were you, I went to the Ft. Washington PA
show and got pricing on the planer and a DJ-20 8" jointer equal to that of
amazon.com, plus free mobile bases, plus the router, and free delivery of the
machines. Good luck.
