go to cabelas and take a look at the plano all weather . they are a bit pricy but well worth it. its not quite a pelican but i can assure yo they are ''60km/h fall off the quad'' proof. when i have expensive pieces of gear, this is what i buy. the locks are solid, the whole case can take good hits. the cut it yourself foam is not fun at all to cut but if you have the one with square tabs, you simply pull the squares and shape your foam so it fits well.
i glued my foams together with 3m super 77, its a contact adhesive. it make a big difference.
