It's a very good budget solution for making flash productions or intros for websites. The only disadvantage that SwishMax has over Flash MX is actionscript. There is a small scripting language within Swish but it's not even close to actionscript in terms of features. Saying that, a lot of the effects that use actionscript in Flash MX are easily generated in Swish using the drop down effects menus.
For the price, I'd recommend it.
