Cutting the cable, lets talk options and media setups

Well, I know Roku has it to where you can either get the box (there are 3 choices) or the stick like Chromecast or Amazon Fire TV stick. I was thinking maybe get the box for the main TV and the sticks for the other 2. Would that be ok or should I just get a box for each TV?

I've used several models of Roku, but I haven't used the newer stick. There is a significant difference in speed and smoothness between the Roku 2 and the Roku 3. If the newer stick is a smooth experience like the Roku 3, go for it, if not, I would just get Roku 3s for every tv. I'm using the older Roku stick in our guest bedroom, the 3400, the one that requires a MHL port, and it's kind of lame, though the newer stick is better I'm sure. The Roku 3 on our main TV is really nice and responsive though.

Perused a few reviews on Amazon, some claiming the wifi range is bad on the stick. I'd be careful if your wifi coverage is spotty. Buffering galore on our guest bedroom tv with the older stick, had to move it to get it to stop.
