I recently purchased an asus n550lf-ck026h and I can't fault it. The design is great, it's fast and powerful, it performs well and it sounds amazing.
However, at the time of purchasing I did feel incredibly unsure about the item, mainly due to the lack of good independent user reviews for this particular model number online.
I threw a quick blog together in which I provide a detailed independent review of this notebook alongside advice for helping you decide if it's the right laptop for you, and start up help to get you set up quickly should you decide to purchase this one.
