I have $150 dress pants that don't fit as well as these.  I love the elastic waist band, not because they let me squeeze into undersized britches, but because it gives a clean fit around the waist without bunching up.  I also like that you can get them in 1 inch length increments.  Also, they have the right room through the crotch - they give space without being baggy, which is always hard to find.  The material is light and airy without being cheap, and at under $40, if it starts to wear thin, you can toss them and get a new pair.
