Insulin pumps for diabetics? ?

My husband has the Medtronic Paradigm. It is the greatest invention ever, short of a cure for diabetes. We've only had it 2 months, so I don't know how the refills are going to work yet. They initially send you 4 months of supplies when you get the pump. My husband has the pump and the glucose sensor, which cost over $6000. Our share of the cost was $65.
