I've only just started to mess with this, but I already love it and can tell this is going to get a lot of use, especially in my sound design-focused sessions.
Even if the only trick it did was the "long reverb," it might be worth the asking price. Basically it just takes the most intense part of a reverb and holds it for a specified amount of time, up to 25 seconds. Very awesome. Obviously, one can use automation of reverb/volume to achieve somewhat similar effects, but this does it 1) much more easily and 2) in a much different sounding way. A way that freezes the sound and just repeats it, but with no audible looping artefacts. I used to spend a lot of time in an audio editor to get effects that I'm getting with this with just a few dial tweak.
It also has the ability to severely transform the input sound. The "bowed metal" preset makes everything sound like, well, bowed metal. Very cool effect with which to create some icy soundscapes. For real, if you're into any genre where you like to create a spacy / barren / cold soundscape, you want this plugin.
One idea for improvement: allow users to type in values, or at a minimum, allow for fine-grain tuning by holding SHIFT.
