re: #26 Love-Child of Cassandra and Sisyphus
Best physics text I ever read was my copy of the three volumes of the Feynman Lectures which are now available for free online. Dead tree is $54 on Amazon.
Last course I took I bought the one edition back from new for ~$40. The new one was, IIRC, $200 and most of the students were happy at how cheap it was.
My hometown school - UW Eau Claire - used to rent students their text books at much saner rates than, say, Madison.
