Its got to be adobe easy to use and the tutorial is excellent a bit pricey though. If you get up and running and if you are looking for work to get you started on it PM me Paul
There are alternatives to Adobe Flash. I use Swishmax, it's a lot cheaper. I found it fairly easy to use. I was going to switch to Adobe, since I use all their other products, but I can really see many benefits to doing so. I think Swishmax is a very close competitor.
