It's very much not-cheap, but I really like my https://www.humanscale.com/products/product.cfm?group=float https://www.humanscale.com/products/product.cfm?group=float Rather than being motorized or cranked, the desk's weight is counterbalanced with springs/pneumatics, similar to a garage door. Adjusting the desk is faster and easier than either a motorized or hand-cranked solution, and is completely non-electronic. The particular desk I linked is quite expensive, there may exist cheaper knockoffs that I'm unaware of. I'm surprised I don't see more counterbalance type sit-stand desks, they're significantly more convenient.
