Yeah I went the "inexpensive" Korean off brand route two years ago. Long story short, these are monitors made with LCD screens made from the likes of LG that did not pass the grade (below grade A) for OEM monitor manufacturer requirements (LG, Samsung, Dell, Apple, etc.). Not only are you gambling with severe quality control as Timeconsumer stated, but you are also giving up extra input options and limited on-screen menu options for calibration.
I wrote a review of my experience with a Crossover 1440p 60Hz monitor on Amazon (model 27QW) back on March 14, 2014 but that entire monitor has been removed from Amazon and my review is gone. If you feel lucky, roll the dice and maybe you will get a good panel if you can live with the single input type (DVI-D for 144Hz speed) and limited on-screen menu options. IMO, they are not worth it.
You will not find a quality 144Hz 1080p 24" panel for under $200, and spending $180 for a Korean knock-off sub-A grade panel is just not worth it, again IMO. If you have a Best Buy near you (and you are in the US) this is about as good a deal as you're going to find:

Finally, always remember the ages old wisdom: you get what you pay for.
