need cheap chemistry drawing prg

I would really like to find an inexpensive (or freeware) molecular drawing program that will allow me to draw small molecules and polypeptides. I don't want to spend $50 on one, as I know there must be an acceptable version of something out there that will do the job for less (I am a very *poor* graduate student). -Drew chemweb: A list for Chemical Applications of the Internet.
