Looking for a Standing Desk with best value for money

Ive been reading alot about standing desks ever since I decided to switch my staff on it. Honestly, more physically healthy and helps with the work energy and productivity. I would be needing about 25 units give or take; so you know why im putting in the homework lol

I like vernal and Ive decided to upgarde my office with it. However, i need to know the best value for money desk I can get since ill be buying in bulk. I hv seen some items on clearance but i reckon they will be limited in number only? Can mods or others help me decide on a desk which is the best value for money? NOT THE CHEAPEST Mind you! but something that can outlive the investment and the wear and tear that comes with office spaces. Thanks in Advance.
