look into the march pumps. I have a chugger pump and im 50/50 on it. There are numerous threads on here about them. Figured i would save your husband the disapointment of his pump crapping out on him. Has been happening more than usual lately and they are apparentely working out the bugs in them.....
Just ordered a march 809 today. I called chugger to see when they would be getting more pumps in and they told me to call back in 2 weeks and maybe they might know when they will have more. I couldn't wait 2 weeks so i coughed up the extra $40 for the march pump.
