Today that you can actually just order online and avoid all the fuss of calling around and trying to find stock. You get a 32GB new Apple TV and an HDMI cable to hook it up with (as that doesn't come in the box because reasons) for $119.98, the cheapest shipping will set you back $5.95, running you up to a grand total of $125.93.
Considering Apple stuff, particularly new Apple stuff doesn't go on sale very often, it seems like a decent deal to hop on... Although, how great of a deal this actually is hinges heavily on how much you value getting the included HDMI cable. It's one of those things that probably costs Radio Shack less than a buck that they can say is a "$20 value" or whatever. You've probably got one laying around, but, I guess it doesn't hurt to have an extra.
As far as the new Apple TV is concerned, largely haven't changed. Gaming on it isn't super exciting as all the games are just mobile games you're playing on your TV with worse controls, but watching video content is a lot nicer. There's a decent unofficial Twitch app, a Plex player, and a bunch of other neat stuff. It's always possible gaming will improve, but I wouldn't make that my primary focus of buying a new Apple TV if I were you unless you're really into Crossy Road. Also, I'm not sure it's worth paying extra for the 64GB version, as I've got my new Apple TV loaded with absolutely everything that even seems vaguely interesting on the tvOS App Store and it hasn't even put a dent in the onboard storage.
