The price I found online for the DC2640 pump was $299 (not sure what you are selling them for) so 3.5 years to break even. Maybe pumps will be more efficient in 3-4 years time as well. If a new pump is required then DC is the way to go for sure, just to replace an existing pump to save money a buyer should do the math first to see if they are satisfied with the possible results. How the pump is being used will also effect the outcome, I'm calculating at 100% 24hrs a day but if a person doesn't require 100% the speed control on the DC unit can be dialed down to adjust flow as compared to an AC pump that runs at 100% all the time and uses a valve to control flow. This would further increase the power savings with a DC pump.

we sell them for 279.00(i believe anyways, im not at work right now ) i agree switching for the upgrade just to save quick money isnt a good financial purchase but there are other benefits as well though when comparing to some larger ac pumps that make these good even if its for uprading.
