I wouldn't recommend that since its an actual genesis controller which means its pretty used. I was suggested this one by a few people and it ended up working great. I highly suggest this one as theyre brand new and work just as well if not better than the originals
There are a few third party genesis controllers that are just god awful, but the one i mentioned is amazing
Hyperkin's 6-button controllers are almost as good as the original. They're nearly identical, and are the best third-party controllers I've used. They're super cheap and it looks like some people get bad ones, but you can always send them back to Amazon if they don't work for you. I've used one for a few years with no issues.
I don't know if this is the cheapest place to buy them, but these are the ones I'm talking about.
