I'm in the same boat, looking for a good stereo pedal. I found a pedal called the MegaWah in development by an outfit called GigFX. It is a multi-featured stereo wah pedal that got high marks at NAMM and is supposed to be released sometime this month. They also make an interesting stereo pedal called the chopper which takes stereo chorus to new extremes. Just google GigFX to find their site and listen to the demo's. Pricey stuff but very nice.
