Sometimes it is not that easy. I went to HD and bought a premium storm door and had a handyman install it reasonable.
In cooler weather we leave the front door open, the storm door locked and it's slider-screen open for fresh air and view.
You will see a lot of CYV that have done this.
P.S.
I have changed doors and added storm doors myself in the past, but decided to sell most of my tools before moving here.
Besides, to me it is not worth the aggrevation of getting the things to fit right.
