I use the Frankford Arsenal portable reloading stands. I have three of them, plus some extra tops. I made one modification. I use carrage bolts to anchor 1/2" X 1/2" screen in the base to act as reinforcing wire. Then I fill the base with acrylic concrete. It adds a lot of weight and rigidity to the base, but you can still take the whole thing apart and put it away.
Not that I ever do it, but you can even assemble it in front of the TV and watch the Super Bowl while your reloading.
