Ryobi calls this a "Precision Bechtop Cutting System" and its abtly named.
This one includes the optional legs/stand plus the casters making this saw easy to move.
Additional accessories include a folding extension table to support work output, and a long fence in addition to the standard fence.
Blade guard is included but not currently installed.
One table top panel supports a router if you're so inclined.
This saw does not disappoint.
