Of all the mini consoles out there, the Neo Geo Mini is the only one with a screen, allowing you to play it on both a TV and in your hands. This makes it particularly unique among the SNES Classic, Genesis Mini, and TurboGrafx-16 Mini, and if you want to enjoy 40 of SNK's best games, then you can do so at a great discount. Amazon has the Neo Geo Mini for only $30, down from its original price of $50. It's important to note this only includes the console and not the mini HDMI cable or any controllers. You can pick up the controllers separately--the white pad is $20, while the black pad is $23.61. On the other hand, a solid mini HDMI cable is only $10.49 on Amazon.
Thankfully, Amazon has a number of Neo Geo Mini bundles available as well, in case you want to snag the entire package in one easy purchase. You can buy the Neo Geo Mini International with two controllers for $73.59. Alternatively, you can get the Neo Geo Mini with a single controller for $49.98. There are a number of other bundles that include both controllers and an HDMI cable in different colour variations, though you will be paying a fair bit more.
