What kinds of music are you looking for?
For what I've got, most of Beethoven and Mozart's Sonatas seem pretty accessible for your level (as long as you don't try Hammerklavier). Same with Chopin, with the exception maybe of his sonatas. Most of his nocturnes and polonaises are pretty good, and if you've played the Estampes, then don't shy away from a ballade or scherzo either. Ravel's Sonatine is also pretty close to the Estampes.
