I love my CSR and use them on just about every project.
They are my go-to verbs.
Well worth the $40 IMO.
Custom Shop.... It doesn't bother me.
It's not like it interferes with my PC and it's stability or anything.
It just sits there quietly doing nothing unless I ask it to.
It doesn't run in the background or fire up at start up like Adobe crap does.
It's basically like an app you would have on a smart phone.
No one really cares if I like it or not. If they want an IK product that's the way you get it.
Waves and NI have similar things.
I even have an iLok and that doesn't bother me at all either. I never even know it's there anymore.
Just my useless 2¢ worth.
