I love my EDM brushes for mineral foundation applications, they range around $7-11ish each. super soft, applies well. I use the long handled kabuki and flat top kabukis.
I love my coastal scents brushes for blush and eye applications, they range around $1.50-15 each. The only brush I have a problem with shedding is a blush brush that I've tried using to stipple/buff in liquid makeup (Saw an EnKore video that suggested a round mop brush so I tried using a round blush brush for it) and it'll shed whenever I use it with liquid, but it's fine with powder blushes. (I've gone back to just using a stippling brush lately.)
I like my ELF brushes, I still grab my concealer brush, shadow brush, and liquid foundation brush regularly. (the shadow brushes are a bit thicker and rougher than my CS ones, but it seems to work faster at packing more color on at once if I am in a hurry). They have two lines, a $1 line and a $3 line. I bought my brushes before they introduced the $3 (studio) line. They're not my favorites, but they still work well enough for me to still use them. Definitely worth at least the dollar though.
I like my Target brushes (both generic Target brand and Sonia Kashuk brand), they run from like $3-20, but I only have a couple brushes from there. Haven't had any bad experiences with those brushes, but haven't had any sort of glorious moments with them, either.
I've spent up to maybe $17 on the larger brushes, but most of my brushes are $1-$5 for eye brushes and $7-12 for face brushes. Great brushes overall, definitely not crazy expensive. No need to go out and spend $50 on a single brush, when you can have an entire set for less than that.
