I replaced my 7 year old awning with this. I have the same one you do. I looked into installing the slats, but realized that they cost more than a replacement awning did.
It is easy to replace the fabric yourself. There are a number of youtube videos out there.
This is a heavy duty vinyl that is holding up well so far. You can buy this one for $150
