If you have an Ulta near you they sell CND Stickey (the 1oz) for about 8 dollars. I -love- CND Stickey.
There's a basecoat by Orly called Bonder that works in a similar manner, they have that at Ulta too, but it's a bit cheaper at Sally Beauty.
I've heard nothing but complaints from people who've used NYC polish. Wet n Wild seems to be stepping up a bit in quality lately, though I still have very few(I have mostly China Glaze, Orly, OPI, etc).
