I've had a tan one since I was a kid. I know we had it by the late '80s, dunno exactly when my parents got it. It shows no signs of wearing out, at least 35 years and a bunch of moves (plus some hard use—it wasn't just a toy box when I was a kid, but a toy itself! And a table, and a chair...) later.

If the new ones are still made like that, I'd love a few more at that price. But I have a feeling the plastic's been CAD'd down to as thin as possible to meet some minimum spec, like with everything else.

[EDIT] Oh, mine's slightly different: the handles aren't a molded element of the outside, but holes through the box itself, with finger-shaped curves. They're great, very secure to hold, though that does mean small stuff can fall out, and they can be tricky if the thing's packed too full.
