The big deal with Pioneer, is that you can upgrade it all the way to Vue Complete (past Pro Studio) by just adding affordably priced modules ($39-99 IIRC). IMO, that's pretty cool. So, if you don't need a feature, you don't pay for it. And if you later decide you want it, you can imediately go to Cornucopia, and purchase and install it.

That said, it appears the servers are getting hammered pretty hard right now....
