I'd also try a local dealer or at least someone on the east coast that sells the cases and allows you to choose a little denser foam than the standard ones come with.
I see that you're from Pittsburgh. I got mine from midwayusa when they were on sale.
But my buddy got his from the Cabela's in West Virginia. and have you ever heard of ace sporting goods located in Washington PA? I believe they have some pelican cases aswell.
Buy a Storm iM3300 instead, the latches are better, the case can be stood on it end with out the wheels getting in the way and falling over like the 1750.
