I recommend these:
https://www.nintendo.com/nes-classic
and
https://www.nintendo.com/super-nes-classic
Looks like Nintendo decided to make enough. Just a heads up, the controller cords are short. I recommend the cord extender pack, they aren't standard USB.
The Nintendo comes with 1 controller and 30 games, the Super Nintendo comes with 2 controllers and 21 games including the previously unreleased Starfox 2. They are about 60 and 80 bucks respectively.
Both come with an HDMI and power cord and look pretty good on a newer type TV. I have a couple of the older systems, and they look terrible connected to a newer non square HDTV. The controllers seem legit. You can't play old cartriges on these, or add games as far as I can tell, but, if you want to play a bunch of old games on something that just works out of the box, these are pretty good.
