I love ecotools, except the bronzer brush. The angle brushes I find amazing, and the rest are medium quality I could see spending more on them with another brandname. They go for $5-$15 each, or the sets of five are around $15-$20. I love the eye brushes, again, the face powder brush and kabukis are medium, foundation brush is a little better, and the bronzer is no. The set of mini eyeshadow brushes is worth it, at 6 for $6 (in canada, at least). I use them whenever I need to carry them on me, or I just don't have time for fooling around with all my brushes.
Also, if you have Icing (by claires), they have three brush lines. Super crappy ones with black bristles, medium ones with brown bristles, and really really high quality ones with brown and white bristles. They all go for between $5-$10ish each, or a roll of five or six for $20. I bought them in doubt, but I love them. The duo tone bristle ones are better than some of my higher end brushes and don't shed at all, the brown ones are better than you'd expect from Icing, and the black ones you'd expect to pay about 50c for.
I also got a roll of seven from Urban Planet for $3, and only the face brush was crap, the rest I use all the time. Not great, but more than useable and helpful to have on hand. They don't have a label, but they were in a little grey/silver/black leopard print roll. I'm assuming they were LA colours, because they only sell LA Colours and ELF there, and they don't look like the only ELF brush I have, and I don't see the roll on ELF's website. I'll look online, see if I can find their brand. (No, I can't, and Urban Planet doesn't list cosmetics online). While I'm at it though Urban Planet always has really cheap basic clothes, like tank tops marked down to $3 and sweaters at $10, so while you're moneyless, you might remember that.
If you shop at Body Shop (if you don't, don't listen to this), they often have promotions with their brush roll, which I really have liked. Usually it's if you spend $30 you can get the roll for $10 or free, and it's a nice and large roll. So, if you shop there anyway (for your skin care or whatnot), wait until that promotion's going- it should be on the website, it's not usually one of the ones up on signs in the store, the reps usually tell you- then by it ll at once and get the roll for free. If you don't shop their anyway, it's obviously not worth it. If you do, it's a good quality five-piece roll with two extra slots, so if you shop there, I recommend. It's not worth the regular price $90, but for free-$10, it's amazing
