Review on Optimized Puroma Microphone Arm Stand: Upgraded Heavy Duty Suspension Boom Scissor Arm Stand with 5 Ties for Blue Yeti, Snowball, and Blue Yeti Nano (Medium) by Brant Skogen

There were cheaper ones but my rather heavy mics made them sag and move. It's not much more in price, but a big leap in quality. They handle my heavy mics with no problem. They're a bit stiff at first, but loosen up a bit over time, but not so much that they cause sagging even with a straight pull. Highly recommended!
