We had the ULine in our Dynasty. Loved that it made ice as quickly as it did. The problem with store bought ice is that it's quick frozen, meaning it contains lots of air. That makes the ice cubes melt quicker. Don't believe it? Put the same number of cubes in a glass from your ice maker and store bought. Cubes will melt in half the time. Anyway, if you're dead set on using the store bought variety, simply use the ice maker as an additional freezer. We did that on several occasions when we bought too much food for the freezer. I would live with what you've got for a few trips to see if you like it more than you think you will....Dennis
