Hi Christine,
Happy to help. I assume he doesn't post on this forum (or we're all in trouble).
Those are good models that work just fine. If you get one with the Spanish cedar shelves, be sure to consider how he purchases his cigars. If he buys lots of boxes, you want shelves more than drawers. If he buys mostly single sticks here and there, then you want drawers to store all those loose sticks.
A New Air unit like that, however, doesn't humidify the space. It just keeps the space at an ideal temperature. To humidify it, you'll still want to buy something along the lines of heartfelt beads or an active humidification unit like the Oasis or Hydra units. I've used both in my own New Air unit and they both work well enough.

Also, if we want to get really specific, your average New Air unit really doesn't keep the cigars at an ideal temperature. Most of the gauges drop the temp to 55-ish degrees. This isn't really ideal for cigars. Not bad, but not really ideal. I also purchased a unit like this one -

Additionally, you'll want to be sure he or you plug the drain hole (usually back corner of the New Air unit) which is how the fridge drains excess moisture or condensation. But in a humidifier you're sort of trying to get that moisture to stay in the unit, and not fall out of it.
Really, all in all, a New Air unit works great, but it isn't exactly plug and play; even the ones that seem pre-set and ready to roll will still need humidification and probably temperature regulation beyond what the device was built for. If you live in a climate that is relatively friendly to cigars, you may want to consider an end-table sized cabinet instead. At least then your husband can focus on keeping it humid instead of keeping it humidified and to the right temperature.
