I have a regular old Crybaby, and its great. But they are really common. Vox is a little edgier, but the best I've heard is the Morley Steve Vai Bad Horsie Wah. It eliminates the akward footswitch by turning it on when you depress the pedal as normal, though its very easy to turn iff off. Look into the unheard of brands. Sometimes there is some really cool stuff just outside the spotlight.
