Decent/cheap HDMI switch?

[Lawyers Guns N Money]

I've got an older TV with only 2 HDMI ports, and I am looking for a decent and CAG-worthy HDMI switch so I don't have to unplug and re-plug in consoles everytime I want to play on a different console.

Anybody have any suggestions?  They have some on Amazon for as little as $8 or so, but I have no experience with what to look for.

I use an unpowered one from Monoprice. Seems to work fine, and it's even lagless.

How does it know which console to send to TV?

I've had this one for a couple of months and it's worked without any issues:

It is powered and comes with a remote.
