Parents have two doors to their patio with the build in blinds, they still function properly and well after years and years of grandkids playing with them. I like them, and my fear was that the internal blinds would get jacked and then your done mode...but theirs have lasted.
Get a good, prehung door, don't do a storm door. They actually don't prolong the life of your door. A good door, one treated correctly for the elements, should last 40 years.
