This product is exclusive to Walmart, but if you're going on Black Friday anyway you might as well impulse-purchase it. Roku tells us the SE is basically identical to the "perfectly good enough" $35 Roku Express (see review link below), albeit with more of a focus on the Walmart-owned Vudu service. And it's white.
Unfortunately the Roku SE is only available in-store at Walmart on Black Friday, Nov. 23, while supplies last.
