I am going to order EZMix2 this week-end. I will report back.
I do not use a lot of effects on single tracks or busses, but, that said, I am hoping I can learn from and benefit from some of the presets since they were designed by very well-respected producers. I will probably immediately turn off the tape delays and other effects that don't fit my style, but I am expecting and hoping for some good stuff out of this plug in. I am pretty happy with Guitar Rig 4 and am not buying EZMix2 for the guitar amp sims, but maybe there will be some jewels there as well.
From the Toontrack site it is $179 USD. From the Sweetwater site it is $149. Both are electronic delivery. I am not promoting either place—just letting you know you might want to shop around.
Note that EZMix2 comes with some basic mastering tools and there is also a mastering plug-in set available for extra cost that can only be used with EXMix2. I am hiring a mastering engineer to do the final masters for my current project, but plan to use in-the-box mastering tools to get decent copies of the tracks for website demos, Soundcloud, etc. (And, hey, maybe they will be good enough...)
