Personally I cant stand the 6 qt tubs. They are way too hard to keep clean, they have to be completely cleaned 2-3 times a week and spot checked everyday. I like the hatchling tubs from Freedom Breeder and Vision Products. I plan on building my next hatchling rack using VP tubs. Hatchlings can stay in them longer and get more established before having to be moved to a bigger tub also, sometimes that move can lead to feeding problems.
