I just wanted to come back and post here that sydinstaller was able to procure another scroll wheel cover for me (all the way from the other side of the world) at an extremely reasonable price. I'm very grateful for his help in getting the part for me (even if it took someone from 9000+ miles away to offer their assistance - makes me even more thankful).

For those of your in Australia, I would definitely recommend contacting Sydinstaller for your CI needs. Great guy! Wish we had a few more suppliers like him around:)
