WSDL->Souce/View Importer issues

For a demo I am looking for stock quote web service, and I found three of them

http://www.webservicex.net/stockquote.asmx?WSDL
http://www.restfulwebservices.net/wcf/StockQuoteService.svc?wsdl
http://ws.cdyne.com/delayedstockquote/delayedstockquote.asmx?WSDL

The first one I see that it is returning the CDATA section instead of result, I get that, the other two failed to finish the wizard for me. One did not let me form the response, another it said WSDL validation.

I tried all of them in SOAP-UI, and they worked to get results for me. I do think these are simple services that should have worked in Designer.
