I side-graded from 6 Infinite to 7 Complete and am so far very happy with the product. I took this path for the simple reason that I can't currently afford the upgrade from 6 Inf to 7 Inf. However, had I known that I would become locked out of a furure upgrade to 7 Infinite then I would most certainly not have made any purchase at all. I can't say I am happy with the situation because I wanted to upgrade from Complete to Infinite as funds became available but that now seems to be impossible. I started out with 5 esprit, then 6 esprit, added the modules one by one until I eventually had 6 Pro studio and then made the jump from there to 6 Infinite. The release of Vue 7 caught me a bit by surprise and very low on funds, so I decided to take take the cheaper option and use Complete for a while as I saved up for the upgrade to Infinite. Big mistake apparently.
