I just got around to trying this, and bought it within an hour. Not sure if the 'sale' is permanent, but $50 seemed a good price.
The additional preset packs you can download for it are nice too.
Being able to exaggerate the Width setting (to 150%) works great with headphones. I was able to get a great room setting with really short decay, and the width setting gave it this really nice 3D vibe with the headphones. I also like testing these collapsed to mono, and it still worked great.
I've been on a room verb bender lately - also having picked up the Fractal reverb and Softube TSAR on sales.
The other plugin that has a great 'Wide' setting is PhoenixVerb (now Nimbus). PhoenixVerb is $10 at the moment (very often) and is another great one for headphone users.
