The best ones I have used have been from Avon (I know!! lolz..) and MAC. My current MAC one is just awesome. It's the wee little one that you can get anywhere that sales MAC.
The Clinique one is awesome - nice sharp tips!! I got it at my Myers and its great.
But if you can get your hands on a NARS one then do - I was given one by a very special lady and its excellent!!!
