I have an older version of this saw and did build a outfeed for it, but not happy with it. I like this build, the author does have to put some holes into the frame to mount it. And I like how the table is spaced out so the fence can go in behind it (my current out feed does not play nicely with this).
I think if I did this build I may reduce some of the size of it.
