I guess the DCS was an improvement over the DCT and the DCP is an improvement over the DCS. It looks like the DCP uses some sort of sine wave technology to quiet the pump down even more than the DCS and DCT. I found a few comparisons and people were saying that some of the larger DCP pumps were quieter than their smaller DCT pumps.
I think that the DCP's are so new that they are barely stocked in the US. The ones available on EBAY are actually not built for the US and can be noisy (according to a few of the sources I have seen). I think Fish Street is the only place that carries the new model that is purpose built for the US.
