Alot has been said already. But I want to share my opinions and experience. I grow alot of trees in large plastic containers, even trees that are beyond the prebonsai stage. Its cheaper, and I can save my best pots for my best trees. However I also use alot of pond baskets or similar, like plastic strainers, and I find that it makes the tree happier, so I would recommend something like that. You can also use pots like these with bonsai soil, or a mix of normal potting soil and bonsai soil, to get better drainage and airation
Biggest issue I find is that the roots require more work when grown in containers like these, as they tend to have a lot of growth going down, and also swirling around the pot at the bottom.
