So after reading some of the reviews on the plug extractors, I wasn't filled with confidence. I'm sure a large portion of the complaints about them is user error, but I still wasn't excited about it. So a little bit more research yielded a product that had stellar reviews.
Here's one of the switch stack screws that broke off. Every switch had at least on break.

The miracle product is called UNSCREW-UMS. Yes, it a corny name. But as long as it works, who cares?
So for $40, I decided to give it a try. It seemed a bit pricey, but if it worked as well as all of the reviews state, it will be worth it.
And here it is after the screw was removed.

The hole is slightly enlarged, but this can easily be filled with bamboo stick, or toothpick. Easy to do.
Here's a look at the product. It comes in multiple sizes. I had to use the smallest size for the switch screw. And see all those screws at the top of the board? Those are from one half of the pf. This product is great!

So in summary, get these screw remover bits. They are worth every penny and work great. Follow the instructions and you'll be pleased.
