Need to move the bulk of my kits for an upcoming project - want to waste as little space as possible.

While Ive been a frequent flyer at the local FedX Kinkos, stalking the excellent boxes that bulk paper reams come in, they are less frequent or they have been flattened, and no they will not save them for me (I asked)

A good commercial box size that is readily available, can still be a reasonable lift size/weight when loaded would be ideal (home center, etc.) or even the excellent U-Line ... looking for your input..

Matt / Dawn what is your preference here - you do it for a living...
