As far as nail polish, I really love Covergirl, Essie and Milani. They're the brands I use the most often. Sephora also has a nice line of polishes called Sephora by Opi.
Also, if you haven't tried glass files, you should! They last forever and work quickly. They're all I've used for the past few years. :)
