Im hesitant whether to buy Flex builder, and I want to make this step from flash to flex. The flex SDK is free, but I do not quite understand how exactly to work with it. It is basically a set of functions I can use, and a compiler? Anyone worked with it, and can refer me to a tutorial, for a helloworld application or something?

Thanks
