So I'm planning to buy a 3x 24inch monitors. But idk how long desk I need. And also, I don't want those stands or things that you attach your monitors on. Just a normal desk for 3 24inch monitors.
You can make one yourself, buy solid wood, the shops that sell it can ussualy cut you the lenght you want for free, here it costs 60€ for 100 inch. Then buy metal legs, they cost around 30€ for 4 legs. so for around 100$ you have the entire table. Then screw the metal legs to the table. You need to also buy the screws.
