This is one of my favourites, at £7.96...it's really very very good indeed.
if you've ever heard of Eventide, one of their guys started Soundtoys, and this plugin is a part of the famous Eventide harmonizer H910
I used it on many BV's and the funky bass that you occasionally hear from me...it adds stereo width and a very tasty doubling, subtle but very effective, to me this is worth more that the £94 full price...
