Personally, I really like NYX.
Thier e/s's are very creamy, smooth and pigmented. There's a large range of colors and it's extremely affordable.
I have about 12 e/s, 3 jumbo pencils, 1 blush in a bright pink color, 4 (unopened) pearl e/s, 5 pigments and an e/s trio in Copper, Bronze & Rust (the trio is my Mac's Spiced Chocolate quad "fix"... I already had the trio and noticed that 2 of the colors are very similar to the mac quad).
I've heard from Pursebuzz that some NYX e/s's are hard to work with, but out of my collection, everything is super smooth & pigmented.
I've noticed that NYX products are sold at Longs Drugstore, Ulta and privately owned salons (I've seen it at an asain owned spa in Northern California). Luckly, Ulta always have discounts (buy 1 get 1 free) or coupons available. Longs rarely have sales for NYX.
