Cost of screen replacement

Hello T@Brs,

Has anyone replaced the screen part of the window system in a 320/400? Any idea of cost? Can the part be purchased from a dealer and self-installed?

There's nothing like falling asleep to a gentle beach breeze, only to be awakened by your awning flying off in the middle of a storm at 3 AM. After the successful recovery of our beloved Marti's Awning, we got back inside and my wife noticed that the pleats were all blown out on one of the screens. In addition to this, some of the openings had torn, where the lines pass through. It's looking shabby, won't collapse properly when the shade goes up, and certainly won't keep the bugs out. 

Any advice would be welcome! Thanks.
