cheap haircut in the Slope?

I'm looking for a place to get an inexpensive, yet decent, haircut in the South Slope/Greenwood Heights area. I'm female, but my hair is pretty low-maintenance -- just long layers falling below the shoulder, nothing fancy. I just want to get a trim and maintain the layers. Anyone know a place where I can get such a cut for $40 or less?

Do a search on the past threads. There's been discussions on this topic and haircuts in general.
Here's a good one:
