OK, in this corner, going for $190: Larson Oxford storm door; wood
core, "dura tech" surface, brass expander (i.e. sweep, I assume),
"heavy duty" weatherstripping; also retractable screen and lock, but I
don't care about those.
And in the other corner, going for $196: Pella Olympia storm door, "1
inch thick solid core", concealed screws, "heavy duty" hinges, brass
sweep, 2 closers, "lifetime storm door protection plan", and or course
retractable screen and lock with lifetime finish guarantee.

So, which one would you buy?

If it makes a difference, I'm gonna make a stab at installing it
myself, since how hard can it be? I've posted the story of the last
time when I had the Sears crew install a storm door, and they sawed up
pieces of the door molding to shim out the oart of the latch that is
on the frame, to make up for the fact that they installed the handle
about an inch inboard of where it should go on the door, so I figure I
can do that well myself. So with sadness I note that the Pella is not
one of theirs with "express install" that "cuts installation time in
half".
