I was watching This Old House today. Tommy Silva always has the newest
tools and toys.

He had this fence for his sliding miter saw. It had an electronic box that
allowed him to compute the fence settings. He then pushes a button and the
fence stop rolls on some kind of track, powered by and electric motor, to
the computed position.

I have no idea who makes it, how much it costs or how durable it is. But it
was very nice. I can think of a few situation where that would have come in
handy

Doe anybody here know anything about this new tool/toy?
