VIVO Heavy Duty Dual Motor Electric Sit Stand Desk Frame, 220 lbs Capacity up to 77" x 43" Tops, Memory Controller Height Adjustable Frame Only, Black, DESK-E-200B

Ikea butcher block countertop - https://www.ikea.com/us/en/cat/butcher-block-countertops-46457/ - they are solid and strong and well priced for what you get. Combine that with motorized legs from Amazon https://www.amazon.com/VIVO-Workstation-Ergonomic-Adjustable-Controller/dp/B08P56RD43 and you have a badass desk. I will warn you - if you put a lot of monitor on the cheap legs, you'll have balance issues when it's at full height - I solved this with a track on the wall that holds it back.
