Price wise? Putting the money up for a Pelican will be worth it when the case falls off the back of a truck or someone spills a 5 gallon container of gatorade on it. (no kidding on those last two.)
Hard cases, tend to be something I avoid cheaping out on. I have a Pelican, and I know what standards to hold it up to, what I can (and cant - which is very little) treat it to.
That being said, here are the alternatives:
Storm cases (from Hardigg. About the same quality and price as Peli)
Zero and Halliburton (less subtle looking as Peli / Storm, usually more $$)
Amvona also has a few, priced well too - just haven't tried them.
There are also cheap versions around
ebay... not anything close to a Pelican but hard enough to take a knock or two. They look kind of cheezy to me and the latches look like they'd easily break. Not sure about size.
