Stila, Lancome, NARS, Chanel, Urban Decay, Bobbi Brown, Biotherm. Well, I use all those now, so...
I'd be extremely sad if I no longer had access to Buried Treasure powerpoint. It's my favorite eyeliner of all time.
Also, Bare Canvas paint is such an awesome e/s base, that I don't even want to apply e/s anymore unless I put that on first. It would suck to not have it anymore, since every other base I've used has been kind of disappointing in comparison.
If not for those two items, I probably wouldn't much care either way, since most of my favorites by them were LE anyway.
