Hi Scott! I got the same Apex stand that you have right now. I've been using it for almost 10 years and never experience any problems at all. I used it with three keyboards before but now I decided to use it with 2 because I am minimizing my set up as much as possible. You're right, never leave your gear unattended coz' a lot of things might happened no matter how strong your stand is. Just make sure you put it in a flat and even surface. Don't set up your stand in between the two platforms they use in the hotel's ballroom, they are uneven most of the time. Don't use it in the cruise line gig. The boat tends to sway in both side and it's not good for this setup. Otherwise, the Apex stand is nice and easy to set up. I saw some of these in different colors. Mine is black but I'm thinking of painting it with metallic yellow or neon blue, kinda like glow in the dark stand. Colors will add your presence on the stage. I can see it'll match with my silver Triton and black Roland controller.
