I have one like the one below. Mine is a higher up model that came with a jaw clamp, extra "feet" to mount a miter saw plus another tool, but other than that it is the same.
I like it because the "outrigger" type supports on each side can slide in and out to adjust for cutting lumber up to 8 feet long. And the supports also have rollers on them that adjust up and down so they can be set level with your saws work surface.
And the "feet' that you attach to your tool stay on the tool, and they also have small rubber pads on the bottom so that you can remove your tool easily from the stand and use it on the floor, or on a table or whatever. Because the feet clamp to the stand, you can position your tool anywhere along the stand.
I have a 12 inch Ryobi miter saw on mine, and when I am done using it, it just rolls out of the way for storage.
I just got done building a shelving storage area in my garage, and this stand worked great holding all the 8 foot 2x4's I was using to make the shelving frames. Without it, I would be trying to work on the floor, or I would have had to take up bench space that I needed for other things. Being able to roll it outside, and keep the dust out of the garage is a bonus also!
Oh, and I don't know if other stands come with this, but this stand has a built in power strip that once you plug the power cord into a receptacle, you can then plug in multiple items into the power strip, eliminating the need for extra extension cords all over the place.
