Weight-wise, the larger EC Protect-it weighs 10oz, the same size (quarter, as I recall) unpadded EC cube is 3oz. The 'hard' isn't so hard that the case won't bulge if you over fill it. It has 2 dividers inside. The current retail price at EMS on the larger EC Protect-it is $25, the smaller one is $22.50.

The biggest concern I've had with EC Protect-it was theft. Mine once wound up where it shouldn't have, where I didn't put it, at the TSA checkpoint. I think I was about to have it stolen "lost". Since then, I leave it out of sight inside a larger carry-on. I think there might have been something about the appearance that said 'valuable worth stealing.' The items inside were worth a bit, but not having a laptop charger at the other end of the trip can be negative 'priceless.'

I changed to using zip lock bags -- less for protection and more to keep things together and to prevent cords from turning into a tangle. Cheaper, and since they are clear, it's easier to see inside.

The 'disposable' food containers they sell near the baggies at the supermarket would probably do the job and are cheaper than EC. My only concern would be the lids popping off if squeezed, something that a decent rubber band should help prevent. I haven't used these much for travel, but they are useful everywhere else, such storing a pile of batteries that aren't in their factory packaging, electronic items with their manual and recharger, and so forth.
