Let's see! I really only use six brushes, and five are from this Coastal Scents set - large angled brush (eyebrows), small angled brush (eyeliner), small shader (eyeshadow), small detail (inner corner highlight/lower lash line), and lip brush. My sixth brush is a MAC 217, which I use every day for perfect blendin'!
I've had the CS brush set for a year and use them nearly every day without seeing much shedding or scratchiness. Definitely worth the money (especially if you think you'll end up using the whole set, instead of just five like me!).
I can't speak for other cheap sets, but I bought this set years ago and it's still amazing. It's not less than $10, but $35 for 22 brushes isn't too shabby.
If you end up trying another set, let us know how it works out!
