The new API is about $2500 from Vintage King here in the states. Not sure what that means for those of you in the EU. I'll be getting one of those early next year.
I considered the Mini before I was decided to get my Massive Passive, but ultimately decided I wanted the full EQ. No regrets! For the filters alone, I think it's worth the extra cash. I did pinch a few pennies by buying the non-mastering edition. Not a real issue, as all the frequencies are clickable and the other controls have more than enough labeling to allow for accurate logging and recall.
