I have CS3 and don't want to pay for the latest versions of Flash or Edge Animate.

All I really want to do is make animated cartoon episodes & post them on my Youtube channel.

With that in mind, what tools am I missing out on by not getting the latest software?

And what problems might I run into by sticking with CS3?

As I understand it, CS3 will allow me to export to AVI, which I can then upload to Youtube. Are there any other considerations that I'm overlooking?

All insights appreciated.
