The NES Classic (which is actually in-stock on Amazon right now) is mostly terrific, but its controller cables are basically uselessly small at just about 3'. Luckily, these 10' extension cables are a cheap and easy fix. This set usually sells for $10-$11, but right now, you can get two for $9.

Add on an extra controller too for $10.
