Just in case you haven't seen/heard or tried the Snazzaroo Dotter Wand here is a pic along with my own 411 concerning it.
Basically, I like it! It accomplishes it's purpose of making a variety of different perfectly sized dots. The size of the dots will depend upon the amount of pressure you apply. It does better with the sponge applicator fully loaded. Cleans well too. I've not had it long enough to experience it's durability, but I think it shall do well for a $5-$7 priced painting tool.
I like this tool as I'm not restricted to it's useage based on the volumn of paint/ quality of paint or it's container -refering to the "Detailz" brand. I purchased it from LaRock's fun and magic. BTW, I notice Snazzaroo has a new facepainting catagory for "Dot usage".
