For the average enthusiast there are too many options with Proshow, however for the pro's it's a smorgasbord.
Yes, it's definitely a smorgasbord for a pro, but this doesn't mean the "average" user can't move on up the ladder. What may happen to a lot of people is that they see the whole thing all at once rather than the smaller, separate pieces. I've mentored a few, not in learning Producer from the ground up, but in helping them achieve this small vision or that. They manage it, and in so doing, gain confidence in their ability to do more. Because of the way the software has been programmed, it's easy to learn it piecemeal and in no particular order.
However, it all depends on a person's goals. Full knowledge of the software isn't necessary, and the busy person doesn't need to invest huge amounts of time in learning before creating a great show. That's the wonderful thing about both Gold and Producer.
