I've owned this stand for 35 years and used it in three different studios that I've owned. It is an absolutely indispensable studio tool if you plan on having a professional photography or videography studio. It works as good as the day I bought it. Counterweighted perfectly to work with heavier camera or even a standard DSLR. I used it for 4x5 work when that was a thing and did a lot of production/catalog work with it. Its perfect to get your set built, lighted, locked down and keeping continuity between shots. The wheels lock as does everything else. I even used it as a rolling stand for video and though it was large and heavy, it did the job. Comes with upgraded Gitzo heads and it has a full 90 degree plus tilt on all axis. If you look at models currently being sold, you'll find they are somewhat inferior in quality and build and they will cost you about $300 just for shipping. This stand has served me well and now it's ready for it's next chapter at your studio. I am firm on the price and not interested in any trades.
I have more pro gear listed here so see my other ads for stands, backgrounds, autopoles, dye sub printers, etc.
