I recently bought a cheap solution for large trays at The Container Store (large chain store). Look for drawer liners.. they come in a variety of sizes. I bought the 14 x 19 " size for about $6 a piece. I like these because they have really low sides, about 4", unlike the underbed storage bins-- they are more like a tray and less like a bin. Also they have very flat bottoms so I can use small volumes. Rocking the tray is really easy.

Small volumes can be emptied back into the jugs, even with the large trays (takes a bit of balance). They haven't cracked yet and don't appear to be ready to. Might try this if you can find a store with drawer liners.
