My first Chromecast i bought years ago for 20$. It's still faster than the Google TV with a remote and I quite like to use my phone as a remote.
LTT screwdriver - although quite expensive has been a great tool when moving a few times, and for everything really.
An old receiver I got used, for 30$ has been with me for 5 years now, and it's sadly starting to misbehave, but I can't afford a new one ATM so I'll suffer through it as it powers everything I throw at it with ease.
