The powder sunblock is really awesome. The elastics are great too, but they stretch out a little easier than the traditional kind.
I can't help with pallets for that reason, I tend to run through colors faster than other and don't like empty pans in the pallet. And, I'm a sworn MAC shadow girl. Have you thought about making you own Mac pallet? It's really easy to do and you can get new pans whenever you need.
Urban Decay Primer Potion is a can't-live-without item for me. I also love their new Naked Skin foundation.
As for palettes, I have a couple Kat Von D palettes that I really like. Colors ate very pigmented. I have Ludwig and Beethoven and have gotten a lot of use out of both. I also have a couple Lorac palettes. I don't love them as much. Seems they have a lot of fall out. Might just be the ones I have, but I'm not sure. Definitely don't use them as often.
I've really been liking Benefits lip glosses lately too. They're really smooth, not sticky.
