title: Do I need Flex Builder?
body: <p>I am completely new to Flex.</p>
  
  <p>Can I realistically develop, say, a medium complex application with the Flex SDK alone, or do I need Flex Builder?</p>
  
  <p>Also, apart from the SDK, what will I need to get started?</p>
  
  <p>Thanks for any help.</p>
