Essence Color & Go nail polishes are ridiculously inexpensive - under $2! I only have this colour - Chic Reloaded - but so far I'm really impressed. For such a cheap price, it goes on really nicely, and dries quickly. You get a nice, opaque colour in 2 coats, as well. I love this colour because it's really neat. At first glance it just looks like a shiny dark grey, but in different lights it has green and purple tones to it. So cool! I think it's a great colour for this time of year.
I think I'm definitely going to have to check out some more Essence polishes, and maybe some of their other products as well. :)
