I picked up the limited edition 10 piece mini nail polish collection. It has a really nice selection of colours. You can purchase full sized bottles as well.

I like the fact that these are mini sized bottles, usually the cheaper nail polish brands get thicker faster, so you end up with less polish wasted. This set cost me around R60 (making it R6 a bottle - great deal). There are 72 colours available in this range so you have a huge selection to chose from.

This polish is not very opaque so you need 2 - 3 layers but some you can see through even then, it lasts a couple of days before chipping, I was really impressed as cheaper brands usually chips fast.
