Stuff has become so cheap that using it rarely is not that much of a problem in practice. I'm not sure where the author concluded that it would cost $22 to get his holes drilled - I'm guessing in SF it would be more. That's not too far off from cordless drill prices ... especially if you're only looking for a drill that doesn't last very much.
