Reddit mentions of Wii Motion Plus - Black (Bulk Packaging)

It sounds like the Wii Motion Plus isn't working right in your controller. There's an old accessory that adds it to a controller - but honestly your safest bet is to get an official Nintendo controller. You can get them refurbished from Nintendo's own store on the cheap.

Wii Sports Club is $40 for all 5 sports - two of them (Baseball and Boxing?) come bundled together. There's also a retail version, which should also MSRP for $40, but may be cheaper used. You could always try picking up the older Wii titles, Wii Sports and Wii Sports Resort, for less money. If you're looking specifically for moving-around games, WarioWare: Smooth Moves (also for Wii) or any of the Just Dance titles may be worth looking into.

EDIT: OH DUH, also Wii Fit/Wii Fit U. But those'll be extra pricey what with the balance board.

Turns a regular wiimote into a motion plus wiimote.

I bought this one. It's first party; works great. https://www.amazon.com/gp/aw/d/B002OL1KEI/ref=pd_aw_sim_147_3?ie=UTF8&psc=1&refRID=07M21M9YM41W9FTH77W1&dpPl=1&dpID=71g7CYZ3xQL

1. get a bluetooth adapter if you don't already have one for your laptop or desktop and make sure its compatible to use with a wii mote
   
   
2. get a sensor bar whether it be USB plug in powered, or a wireless sensor bar, or you could even leave a wii running (waste of energy) with a sensor bar connected to it
   
   
3. Get a wii mote and nunchuck
   
   
4. get a wii motion plus add on

The wii-motes will work just fine in every game that doesnt require motion plus. A game that shows this well is nintendoland, 2 of the games require motion plus, but all the others work fine without it. Motion plus is also available as an accessory so you wont have to buy completely new controllers, it usually costs about 5-10 bucks.

The motion plus adapters appear to be slightly cheaper in the long run, but I would just buy refurb from Nintendo.
