That depends. I think Infinite is worth it....but I also use it as my end stage renderer for animating. If you go with Esprit, you can buy the add on modules as $$$ permits; when you get done, you wind up with Pro Studio (You won't have Python script support, and the ecosystems module is basically the one for Vue -5- Infinite.....but othter than that, you would have a pretty robust solution). And the best part is that if you decided to move up to Infinite, you could wait for the next version and take advantage of the upgrade pricing that e-on usually offers to early adopters.
