Ibayley - buy a roku3, because it's better than the stick. Some channels cost money like this article states, some channels are free, some channels require subscriptions to cabel or satellite some channels are good some are junk. Would you like someone to go through all 15oo channels?
My suggestion is to go buy the roku, then return it if you don't like it.
I'm still shocked sometimes that people need their hands held for everything now adays...
