Replying to Best budget 24mm prime?

looking to get a better general use photography and videography lens for my t5i (looking at 24mm full frame lenses to get a 38mm FOV) and i was wondering if you guys had any suggestions or if anyone has owned any particular one. I am very interested in the rokinon-samyang-bower 24mm f/1.4, but i have heard of many copies become de-centered in focus making it unable to get sharp images. i would like to keep it in the sub 500$ range otherwise i would love to get a sigma art 24mm or 18-35mm. thanks!
