I just got a red panda particle, often referred to as a delay, and it can be a straight delay in some settings, is more a sampler. The sample and pitch shifting type effects it does are strange and wonderful. Red panda lab, check it out.
A new toy in my delay box is the Diamond Quantum Leap. Very unusual feature set; all kinds of musical time and pitch bending possibilities between 12ms-600ms. All the wackiness happens with Diamond's amazing tone quality, too.
