With seven different version of Vue 7 ranging from $49.95 to $1495 USD there truly is a version for everyone and considering what this product can do, each are well worth the price.
If you are still not sure, try out the free Pioneer version. You can get a Personal Learning Edition (PLE) of either Vue 7 Infinite or xStream that are full versions that never expire. The only restrictions are 1) that it is not to be used in commercial products, and 2) that the renders will contain a logo and a watermark for sizes over 800x600 and after 30 days. But if you want to learn the software, everything else works.
From a personal point of view, this is a fun product. Really, very easy to use, and if you are fearful of how hard it is to learn, just Google "Vue Tutorial" and you will find all sorts of cool things that you can do with it. There is also a new book that I have recently reviewed called Vue 7: From the Ground Up that walks you through the Vue system very nicely. I very highly recommend the Vue 7 product line, and especially Vue 7 Infinite.
