Pelican case, should I? And if so what size?

I figure get the largest that is allowed on a plane as a carry on. The Pelican 1510 which is also a roller. Never know when you would need all the space but you don't want to go so large that you would be forced to check in. It should also be big enough for those car trips as well. Mine is used all year round to store equipment. Make sure you get the divider set instead of the pluck foam. I once travelled "lightly" and had a change of cloths inside with my net book too.

 

I suspect the size would depend on what you were doing with it. In my case I have a Pelican Case that I use to take canoeing with me. Because we were wilderness canoeing I got a case that was just big enough and no more, as I do hate to carry an ounce extra on portages. Mine was big enough to carry a Nikon F5 with two lenses a small flash, lots of batteries, a few filters and all the film I would use. I don't suspect you are doing the same as I did so just figure out what you want to use it for and let that determine what you get.

An in case you wonder how good they are, I set my gear upright next to a slope, and our rambunctious dog knocked it over. It rolled, hopped, skipped, jumped, and fell almost 20 feet and landed in a lake, I retrieved the case mopped it off and opened it up to see that the gear hadn't even moved a bit. For rough use it is the best bit of camera insurance that I ever bought.

 

check these guys out. You can find a case based on dimensions and they also offer custom foam service. I used them last year and would use them again.
