Terrific price. I would be all over this except needing RCA plugs to attach my dvd player.
great price but no vesa mount 
If you have Amazon Prime it’s only $15 more for a brand new one. http://www.amazon.com/gp/product/B00M2UIWKQ?keywords=S24E390HL&qid=1457483811&ref_=sr_1_7&s=pc&sr=1-7
Edit: On Amazon the model is S24D300H. The stand appears to be different.
This should work but it adds $32 to the price:
