The steel won't bring alot. Its the motor and and the wiring that are worth some. If the controller still works you can try selling that on ebay. I have bought a few that way to keep my current one going.
The difference between an optimist and a pessimist is that the pessimist is better informed.
If the heating element and/or motor are good, sell them on craigslist or ebay. They are worth much as replacements than scrap metal. A new replacement motor can run anywhere from $50 to over $100. Getting $20 to $30 for it should be easy.
As n082s said, yank out all the wiring. In high amperage applicances it is nice thick and heavy copper.
