As mentioned earlier, I am using a weighted Lee stand and I find it works quite well. The tripod design is more stable than similar weight tables with four legs. Because the Lee is also narrow, it is stiffer in the verticle direction that if similar legs were supporting a much broader surface. The three legs don't look especially sturdy, but realize all three are supporting only the little triangular press mount plate, not a big work surface that can exert more leverage.
The Lee does not seem to flex in the legs. With weight on it, it does not move either. What does appear to happen is the steel base block, which is the quick-change steel plate the press mounts to, flexes. This is a 9/64" steel plate. I've tried putting washers under it (between the base block and the top of the press stand) to limit the flex, but it still flexes some.
The Lee stand also vibrates. This is going to happen with a stiff material like steel. The only way I can think of to stop this is to dampen it with a softer, more flexible material, or to increase the mass. Just using the concrete block and much lead weight on the shelf does not fully dampen vibrations. I have a much more massive 20-ton shop press, and it can still be vibrated with a light hammer blow. I would think a mass closer to 500 pounds would dampen better. I want to cast a press stand from reinforced concrete.
