The PitchFactor does have some great chorus sounds, as does the Time Factor. But I'm assuming a straight forward chorus pedal is more in line with what the OP wants.
If you're on a budget, the Zoom MS70 CDR has some pretty decent chorus models on it. Among them are clones of: MXR Analog Chorus, TC Electronic Corona (both regular and tri-chorus modes), Boss Chorus Ensemble and CE-5, as well as a bunch of others. Not bad For $120.
If you want more digital options and sounds: Eventide or TC electronic bring the goods If you want more analog sound: I personaly like JAM-pedals Waterfall
EDIT: With that said if you are endorsed by Wampler, I would have taken that. Didn't try it but they do great stuff and I guess it will be in the same ballpark and match almost everything else out there.
The Moog Clusterflux. It is hands down the best chorus pedal. Ever. The axe fx can't even come close to what it can do. But then again, it's nearly $500...
