i just got the legs from amazon and slapped a butcher block on top of it
I don’t own this myself, but I have seen others recommend this one
TOPSKY Dual Motor Electric Adjustable Standing Computer Desk for Home and Office (Black Frame only) https://www.amazon.com/dp/B08C2LC3H2/
Topsky has a frame that I just bought. I spent 4-5 hours reading reviews, looking at pictures. Ran the page through a fake review detector and it didn't detect any.

That is TOPSKY dual motor frame link
I’ll take a pic of it at full height in a few and post here.
I slapped a butcher block on top of this guy from amazon.
I guess it can be wobbly if you shake it, but i haven't noticed just working on it
