+1 for the Ridgid MSUV. I have a 12" DeWalt sliding miter saw, and started out with the DeWalt DWX723 stand for it. The stand worked fine, but it had no wheels. Which meant every time you want to use the saw you have to lug it around by hand, and it's heavy. Plus lug the stand separately. Plus find a place to store the saw flat off the stand, and then hang or store the stand.
My saw stays permanently mounted to the MSUV, it folds up and sits in a corner of my garage and takes up less room than if I had to have the saw sitting horizontally. Rolls around very easily, has nice big wheels if you're going over terrain at a job site. Loading in the truck I put the handle of the MSUV on the tailgate, then lift by the end by the wheels and slide it in. This method is pretty easy, and you're really only lifting half the weight or so, which is very manageable. For me at least I just find it way more practical.
The Bosch stand would have also been my first choice, but the MSUV does the job just as well for much less money.
