Looks like I found a couple of winners! Sterilite RE Organize XL (for smaller) 14in x 11x 6 1/4 Without the lid. And Sterlite 25 QT (for larger) 24 3/8 x 15 1/8 x 6 1/8 with the lid but without the locks.

I ended up just going to Target and Wal-mart and buying a total of four different tubs to take home and try out. The large was from Wal-mart and the small from Target. It was impossible to go buy dimensions only because they include the lid and the size of the lid makes a huge difference.
