Rubbermaid snap cases all the way!!!!!!!
They kinda look like suit cases and come in 3 sizes and a few colours (clear and clear blue are good). They lock with snaps so you don't have to worry about taping or putting weight on top and that kinda crap.
The biggest one is great and has a locking handle that your bp will spend countless hours going back and forth in between! It's about 20"X 14" X 8" H.
The small one is good too, and it doesn't have such a scary top-down approach as most rubbermaids/serilites. Those are around 12"X14"X 6" H.
(trying to find a picture) biggest not shown here.
But I also have sterilite and gracious living containers for the bigger stuff..... anything that needs more than a 30 gallon rubbermaid gets an enclosure.
