Do you have any recommendations for a whole house humidifier?

We are considering adding a whole house humidifier to our current furnace/central air system. We had an Aprilaire (sp?) brand in the condo years ago and it seemed to work well. We will consider that brand, but I was wondering if any jellies had other recommendations.

If you do have a recommendation, what did you like about it? How long did it last?

My husband is researching this too, but I thought I would ask the collective as well.
