I suppose it's maybe a matter of understanding what will get you a decent return on your investment.

To the car example, I've done a moderate amount of work on my car in the past year. When I started, I had a junk set of sockets and wrenches from Walmart. I had a socket split in half when I was trying to loosen a bolt. Obviously the tools I had weren't up to the task. So I went to the hardware store and bought Crescent brand tools. They work great for a hobbyist like me. I don't do nearly enough mechanical work to require SnapOn or similar professional-grade tooling.

So I guess my critique is more, does this guy do things that require the top of the line tooling, or is he doing it just to showboat?

From other things I've read here, I'm reasonably convinced that he is probably justified in spending on the things he did. I didn't have any of that background when I read the article and made my initial comment.
