Thanks for your interest in CS-STRIP87.
The plugins of the ANALOG87 Series are low priced for historical reasons.
The first version of these plugins has been released in 2010 (32-bit VST for Windows only then).
They have been entirely re-designed, re-coded and improved about one year ago in order to provide a solid set of dynamics/EQ tools for Windows and OSX (32 and 64 bit).
In 2012, a first review has been published by buenasidea.de and then Computer Music and more recently Future Music published amazingly positive reviews about them (4 awards, ...).
However their price is probably the only thing which has never been updated in two years :-)
The idea behind the ANALOG87 Series was to provide efficient but intuitive mixing tools that respect the charateristics of the audio source they receive. They are often described as "smooth" processors (which does not mean "light"!), as they have been designed to avoid digital artifacts.
Please feel free to give a try to the demo version.
