Seeking info on Gaylord Boxes

So I've heard a lot about these gaylord boxes. I know what they are because we used them at a PCB manufacturer I used to work at. My questions are more related to the how to's.

First, once I get a gaylord box full, packed, and strapped...is a forklift the only way to move it? Do I have to have one of my own, or do whoever picks them up usually bring a moffet truck of some kind?

Second, where is the best place to get them that you have found? Best size? Shape?



And Finally, any tricks I should know or tips on how to use one in the most efficient manner?

Thanks!
