Brew your own to see what good beans really cost.

Start with one specific thing you want to learn.

You're right about old stuff working until it doesn't. My own router is probably that old, @karen_wilson. I keep meaning to replace it, but it just sits there quietly doing its job. The day it finally quits will be a real pain, but until then, why fix what isn't broken? It's a good lesson in not replacing things just because they're old.
