I'm looking at Harbor Freight to replace my junky old Craftsman boxes, so I would say it's worth it, but I haven't bought them yet because I'm thrifty, AKA cheap.
Organization is a dream but is difficult to maintain as I always have too many projects at once, and every flat surface gets piled on.
Check out HF though, they have lots of sales, I looked at the boxes in person and they looked good.
