Fleisher Art Memorial has reasonably priced classes in a wide variety of arts.

From the website:

"The unique approach of Market East is to feature rare and limited edition works by underground artists alongside pieces by more established artists. The result is an eclectic mix of slick, professional pieces with those that are more raw and handmade. We sell books, zines, screenprints, posters, t-shirts, postcards, and music.

It's more than just a store, though, it's also an online gallery. That's why things that sell out often remain on the site for a few months. This way visitors can still enjoy the images and be inspired by the piece. For many of the artists on the site, this is their only significant presence on the web."
