You beat me to this post.
My starphire tank has a decent gouge down the center of it, and it's noticeable. I was going to try to buff it out, but since it's as deep as it is, there was no chance it would come out (anything you can "feel" with your fingernail is supposedly too deep to polish out).
Starphire (to my understanding) does scratch easier than "regular" glass.
So. There you have lots of different opinions and hopefully some useful information.
Let us know what you decide...

Well, not quite true. You definitely can scratch glass, especially Starphire. It's just harder to scratch than acrylic. The major difference is that you can easily buff out acrylic scratches with the tank still filled but very hard to do to glass. Not only is it hard to remove glass scratches, but you'll have to drain the tank.
