Used Spinnakers

I find that a Cal-34 has about the same size spinnaker as what I need for my Lapworth-36. I am looking for something I can learn with. I have a very old one that I will use, but it is very old... It is cross cut and looks a lot like this http://l-36.com/image/spinnaker_intro_Papoose_spinnaker.png Does anyone have one sitting in your attic that needs a new home that would be a step up from what I have?
