Of course there are a million substitutes for this product and I am no gear snob - if it looks the same and feels the same I will always take the cheaper option regardless of brand. HOWEVER - this product feels and looks nothing like its competitors! Chroming is perfect, the shape is exactly symmetrical and the weight feels right. Also, unlike its competitors, the angle of the cable comes out MUCH lower to the body - yes this costs more but is absolutely worth it. It comes with screws for installing too!
Take my advice - this product looks better than the rest - you don't want to be putting cheap chrome on your prized guitar... just like you shouldn't be wearing fake jewelry to impress people!
