Alternative device?

So I have a shield, it is phenomenal for streaming. I love the processing power and it puts the firesticks we have to shame as far as speed goes. That sd, I can't justify paying for 3 additional shields for the house. I would however like to have a "cheaper, less powerful, but faster than a firestick" alternative? Any suggestions? I tried looking at Google TV but I couldn't tell if it's faster than the firesticks we already have.
