<p>I'd agree with momrath's list of schools similar to Amherst, Williams, and Pomona. Furthermore I would add to that (and some of these are a bit less selective) Middlebury, Swarthmore, Oberlin, and Vassar. Vassar, Oberlin, & Swarthmore are more liberal, Brown-like sort of LAS while Middlebury is similiar to an Amherst-Williams type of LAS. At least, that's my take on it all.</p>
