I had one for about seven months last year, while doing the Folfox routine. It truly is a godsend, given the difficulties many people have with collapsed veins, etc. I just thought of it as my little docking station, it makes it easy for blood testing and the many different shots of liquids that prepare your body for the chemotherapy.
You didn't mention whether your husband was going to have the pump to wear overnight. I hauled that little jerk around for 48 hours every two weeks for six months. Got to where it was not my friend, because I grew sick of the little buzzes and clicks at night, and the tubing kept getting caught on things around the house as I became more accustomed to dragging it around. If your husband is going to wear the pump as many of us do, I can't imagine having the infusion any other way than through a port. I really don't think he'd want the typical vein infusion taped to various parts of himself, the port made the pump palatable. The only trick is that you need to remember to have him shave the area of skin under which the port is placed (in my case above my left breast). The tubing and needle arrangement works great, but it is held in place with really sticky tape and that's no fun when it is removed...if there is hair there.
They can generally draw blood through the port, so you don't have additional needle sticks for that. I'd say that generally a port is our friend. Some people don't like having theirs taken out, even, because they feel like they've grown a new buddy. But they need to be flushed fairly frequently if you aren't taking chemotherapy through them, so I was just as happy to get mine removed when I was done.
