Hey Quibbley,
I checked out your Craigslist ad and I think your asking price of $700 is scaring people off. I have consulted two recent price guides and they agree on a value somewhere between $350-$450.
It would probably also help to add some information about age and condition to your ad. These Tornados were produced between 1965-67. A few words about playability, wear, etc. might also generate more interest.
Instruments like this can normally ship within the US through the USPS for under $30 insured. The biggest obstacle to shipping is finding a good box. Your best alternative is to stop by your local guitar dealer and ask them to give/sell you a guitar box.
good luck
