That's why I said that you should see the other threads... There's much more information there than on the comparison table. ;-)

For example, one thing that could be important for you is the (currently hardly existing) upgrade path from Vue 7 Complete to Vue 7 Infinite, in case you want to do it later. This topic is in discussion in another thread.
There's also another thread with the list of plants with which Infinite and Complete are supplied (in Infinite there's many more, and that can be translated into money, but maybe you already have most of the plants that Infinite has).
Etc, etc, etc.

If you want an informed decision, you should really see the other threads... :-)
