Repair Keyboard... 0/140th of the cost: Check

Our MacBook Pro had a broken key on it, due to an individuals archaic repair, the the "Key Nipple" (an actual computer part term) was ripped off the key. I took it to the Apple Store expecting a quick and cheap repair. It was only a small piece of rubber that needed replacing right?
Wrong they told me it would cost $140 bucks. They would HAVE to replace the entire keyboard.
I went home and did this.

This is the broken key. Without a nipple.


This is a nipple I removed from a much older laptop, sitting on the razor blade I used to cut it out of the old laptop.


This is the new nipple (from the old laptop) placed in the hole left by the broken nipple.


Here is the delete key, re-installed over the replacement nipple.
The notion that they wanted me to replace the entire keyboard, a $140 expenditure, over maybe a ¢10 piece of rubber/silicon is absolutely ridiculous, and not to mention wasteful. I love Apple products and their software they continue to excel over all their competitors, but for a company that boasts "The Greenest Family of Notebooks" to be so wasteful is ridiculous.
Here is a video of the fully functional delete key in use.
