Frenchy, I got a wooden screen door at "Home Hardware" for just $29
It's really basic but does the trick. They have a variety of widths available (my door is an odd size so I had to shave one down).
I guess regular price is $39,99 but they should be on sale this time of year.
old doors seem to be everywhere.. until you are trying to find one
