I have to chime in on the "high-end toolboxes are too expensive" comments. I'm fairly new to the forum but I'm surprised at how many folks keep putting down high end boxes. I suspect it's really jealousy talking, but what do I know?
The high-end market for everything from vehicles, to toolboxes, to watches, is always more expensive than the cheap stuff. Some people find it worth the money for them, and other people choose to spend their money elsewhere. For people who really want what they think is the best, they'll pay for it. For high-end toolboxes, the market seems to support the price, so, by definition, they are not "too expensive." Too costly for some people? Sure, and that's fine. Those people don't have to buy them.
Speaking as someone who has never had (but hopefully will some day) a high-end SO box, I actually find tools and toolboxes some of the most worthwhile expenditures, especially by people who make their living with them. If you spend all of your time making a living working out of a toolbox, it makes some sense to have a toolbox that you think is the best one you can have (provided you can afford it).
On this forum I've seen tremendous graciousness toward new young mechanics just getting their first beat-up old box. People are happy for them, appreciate what it takes to get started, and wish them happiness in their purchases. The same graciousness should extend to the folks are similarly excited about their new toolbox acquisition. They're happy, I'm happy for them.
And once in a while, someone will get in over their head in their purchases...and some of us will get deals on CL.
The original poster seems to have gotten a good deal on a nice box. Congratulations, and I hope you enjoy it.
