Well, Pro has several advantages in the handling of the scene, particularly about the placement and use of lights, and about the handling of the models. For me, they are worth the difference in price, for other people maybe they are not. If you can make only one expense, I would suggest perhaps to learn Vue 4 better during the next few months, and for Christmas, to buy Vue 5 Pro, since it will be released at that time. If you can spend more, then you could buy Esprit 5 now and sidegrade to Pro at Christmas time. Beware though, you'll spend approximately $400 more, if not even more probably ($150 for the upgrade to esprit 5 + at a minimum of $250 -my guess here- for the sidegrade from Esprit 5 to Pro)
