I know the DCS356 is the newer model and has a 3 speed switch. Are there any other differences at ALL? Is there a power or vibration difference etc? The weird part is the DCS356 appears to be cheaper than the DCS355 which doesn't make sense if it's exactly the same with a 3 speed switch. Thanks!!
(I know about the Atomic model DCS354. I am not interested in that one)
