The problem was suds being very strict about the wsdl definition, and there technically being a bug in their wsdl. I'm no expert, but try altering the amazon wsdl by adding this: <xs:import namespace="<a class="moz-txt-link-freetext" href="http://webservices.amazon.com/AWSECommerceService/2008-08-19">http://webservices.amazon.com/AWSECommerceService/2008-08-19</a>"/> to line 5, which is currently blank.
