Storm Door Recommendations

Looking for Storm Door recommendations. I have Home Depot and Lowes near by not that I have to buy from them but they are there. Looking for the best bang for the buck or best value. I have a regular sized door from a very common Raised Ranch type home in sometimes frigid North East/New England area. . Are there any particular features I should be looking for? ....as I have replaced every single window and door in my house I am pretty confident I can knock this out in an afternoon. :)
