LA Good Question: Cheaper Version of this Mirror?

Pin it button big

This would be the perfect mirror for above our friend's mantle. It's the epitome of simple and chic but the price tag is a little high, anyone have some cheaper alternatives?

Room and Board's Infinity Mirror Collection is highly covetable but the round mirror is nearly $600. It's sleek, it's modern, it isn't in your face. Have you seen anything similar for less?
