I've got some old school synths and I've worried that previous keyboard stands weren't up to the task of holding three of them. The IQ3000 series is significantly heavier and heavier built than anything else I've seen. It folds easily and has a modular shelving system that easily allows me to stack 3 keyboards. At $350# the weight rating is adequate for anything I'll throw at it. And at less than $100 it's really a bargain!
