Which tool chest should I buy?

First off, I wouldn't walk across the street for a current Craftsman box. Too "tinny" for my likes. As to the Snap-On, it depends entirely on condition. The last plant I worked at replaced the mechanic's Snap-On boxes with Proto and offered them to the employees by auction. There wasn't one worth having in the bunch. Just worn out and beat up.

So, you have to ask yourself, are you in the market for a box or a project? Of your choices, I'd go with the Kobalt, or another similar Kobalt.
