NBO oneboard alternative

Hello everyone. Perhaps it's just me, but my Instagram is absolutely full with NBO one board advertisements. And it looks great, but the cost is insane.

I'm a big fan of clamps etc and love the idea of applying it to some of my gear around the desk. But I also love a bargain (thank you to IKEA for the peli dividers).

Has anyone found some good bargain methods to ergonomic workstation accessories around the desk?

Cheers!
