I have to agree and have a large amount of them for Retro gaming and computer equipment. They are the best on the market, but yes, expensive.
There are two types of people... Those who have bought really useful boxes before and now only buy these... And those who have never tried them. They are a middle ground between a normal storage box and a peli case. Really quite tough, but not peli tough. We use them to store rally gear where they won't get as much abuse as a peli...
I understand your point but I'm this case I think many people would be happy to take that risk.
I have cheap Wilkinsons ones that have been going for several years.
These are great boxes and 4 for £15 each is a bargain
