Steve - I have the Studio bundle, which is the recently updated bundle with Ozone 5, Alloy 2 and Nectar 2.
The Nectar 2 tutorial is for sale only on the iZotope site in their store. The tutorial is very detailed and shows numerous nuance settings for the harmonizer in Nectar 2 that are not at all apparent from watching the promo videos. To be honest, I don't like the tutorial company of this so much because they have a strange platform for watching their material - but the content of this tutorial is excellent and it is very helpful.
Although everything about this bundle is working like a charm for me and "as advertised", now that I've been working with Alloy 2 and see what it can do, I would have spent the same amount for the full bundle just to get Alloy 2. The funny thing is, I bought the bundle specifically for Ozone 5 and Nectar 2, both great and I'm wowed. I just got the included Alloy 2 as part of the value. Then I tried Alloy 2 - and I fell out of my chair in surprise.
