I have looked at several mobile file folding carts similar to this (
http://www.officedep...e-Folding-File/) but all seem to be junk. Cheap, flimsy, and thin plastic seems to be the norm. They might last for one use and then they're ready to be tossed in the dumpster. I have a few milk crates at home and know they can take a good bit of abuse. All the crates I have on hand are oily so I purchased these from Amazon (
http://www.amazon.co...rds=milk+crates) and a cart to roll the crates into the testing site. This is the cart that I purchased (
http://www.amazon.co...s=personal+cart). I've gotten lazy when it comes to physical labor and I don't like lugging heavy things around. This seems to work well for me. I wanted something that will last beyond the exam so this seems to fit the bill. The extra crates are nice for storage for all that Christmas decoration stuff my wife has.
