I've been struggling to find a 27 inch external monitor that deals with the "blurry text" issues with my Macbook Pro Retina and I figured I'd ask here to see if anyone has any recommendations.
I would suggest you to check Lenovo ThinkVision LED-lit Monitor for your MacBook Pro. It will come in your budget and it is considered as one of the top-rated USB C monitors for MacBook.
VERY happy with my LG 5k. BTW I'm using this with a Belkin dock and external keyboard and the whole set up is really elegant. The mbp keyboard is loud and clackety - don't like that part of the machine at all. 🙂
