Best tubs for breeding Ratsnakes

Hello everyone! I have been away from the forums for quite a long time, but I recently started looking into making more racks for my snakes and was wondering what plastic tubs are the best (and most preferred) for keeping adult breeding size colubrids? What is the preferred tubs for keeping younger snakes?

I have used a variety in the past, but am looking to move all my animals into one consistent size/brand and want to find out what the best one is. Your opinions will be greatly appreciated!

What brand/model tub do you prefer and how much do you usually pay per container?

Thank you!
