Have you checked out this nail polish brand at Walgreens? Obviously, it is called Sinful Colors Professional. I have a few colors from this brand and really like them for the price! Purchasing any of the colors from this line will only cost you $1.99 and any of the treatments are only $3.99! THAT right there is a STEAL especially for the quality you get.
Personally, I don't like super thick polishes, it makes it pretty difficult to apply 2 thin coats, which is what I do (drying in between). This formula isn't as thick and goopy as some brands, but that doesn't mean you will sacrifice pigmentation and coverage! The lighter colors and the matte shades they have won't generally apply with one coat and give me the opaque look I want, but most of the normal, everyday colors will if I am in a rush. I have never had issues with streaking and the color is generally even throughout the entire manicure. The brush offers decent control around the cuticles because it isn't ginormus, so I didn't make too big of a mess this go around! LOL!
