Sorry, I'm not a potential customer, but this is a great price. I'm doing a lot of post mixing along with some music mixing and composing and I wouldn't like to live without Altiverb (snapshot automation is a godsend). On the other hand, I do understand that Spaces II can be awesome just for music. And it's good to know that with Altiverb you're paying mainly for a vast number of great IRs and new impulses are still often added to the already very comprehensive collection. All in all, this is The reverb plugin for post and a very nice one for music.
