for the Brush painter you can not beat vallejo hands down in acrylics,

I have the rust set from lifecolor so i cant comment on how well they paint on a larger surface but i do know  i prefer them unthinned, the plus to them is they are very easy to clean and you can thin them with water.

oh and dont waste you time with there ab cleaner i tried it and it cloged up the ab so now i use it as brush cleaner and it works relly well for that,
