4R-140B : Rock solid and Rolls too (its on wheels)

To solve all problems..........Throw money at it...

And that applies to keeping a bunch of keyboards stable and playable with the added bonus of moveable.

I am using mine in a studio setting but need to move it occasionally to access a storage cupboard and it works great.

It is very light weight considering its size and should be no problem carting to gigs,

( I am not saying you should actually cart all your keyboards on the stand down the road to your local venue, that would not be good )

How all the fasteners last over time is a lot down to how you treat them. (Never let a drummer tighten up the bolts)

I like the design of this rack, I have had the A frame style before and this is much more stable and you can place it closer to a wall.

Expensive but works.
