I've been very happy with the EcoTools brush sets I've bought, the brushes are so soft! (I do not recommend their foundation brush tho, I think I bought that separately but it's been the only one to fall apart on me)
The only ELF brushes I like are the fan brush and smaller eyeshadow brushes.
You should go to your local craft store and check out what kind of paint brushes they have, I got a couple great eyeliner brushes for like $4.
