Smallest available resin printer?

What is the resin printer with the smallest build volume (smallest by the LCD screen) I know tinymaker is the smallest but I won't get one shipped until January.

My reasoning is because I want to make swatches of colors I mix as I'm experimenting with different dyes and such. I would like to be able to mix a very small amount. The tinymaker would be perfect for this use case but it's not readily available
