FWIW I went for QuickQuak's PitchWheel effect (the 'elastique' was considerably more expensive).
It's pretty damn good I have to say and maps really nicely in ACT to my PCR-300 (although I couldn't get it to ACT-learn for some reason, other plugins ACT-learn just fine so something's a bit odd there). It automation writes and reads as you'd expect.
There are demos of both available I believe.
