Hint: The best fences invariably lock down, ONLY in the front. That way,
you can add extensions to the outfeed, at a later time. The Shop Fox locks
in both the front and back and while my SF fence always locks parallel and
straight, it's still a PITA because I can't figure a way to make a outfeed
extension without some serious work.

The standard SF fence that came with my 1023SL locks only
in the front. There were discussions here about the differences
between the "standard" and "deluxe" fence. IIRC, most felt
the standard was better in that the deluxe was too fussy to
keep right. I am very happy with the standard - it is
rock solid and true.
