I'm aware of MyStuff 2, Home Inventory, Compartments, Bento, Delicious Library, etc. However, none seem to do exactly what my fiance and I are looking for. I'd like to be able to take most of the inventory on my Mac, but access and add to the inventory from our iPhones and iPad. A UPC scanner would be a major plus, as well. I'm well aware that a quality option will most likely not be free, but I don't want to spend $60 either.
