I thought I'd give a heads up to anyone who was reading this post:
I went ahead and ordered one of those cases a few posts above me off of the Hong Kong ebay seller. I chose the clear variety. Like the OP I too have been looking for the perfect clear case that's not a hard plastic that scratches, and not too flimsy like thin silicone.
I thought this case looked promising...I was wrong. I received it yesterday after 10 days shipping, and was severely disappointed. It is not soft at all, it is a hard plastic much like the Power Support Air Jacket Clear, just not as nice quality. It's a tad thinner perhaps, which is why that picture shows them bending it, but it is by no means "soft" or rubber-like. It was simply a cheap Air Jacket, and had a really poorly cut camera hole.
At least it was cheap, and free shipping - so I didn't waste too much. But be warned anyone looking at those ebay cases thinking it's like a softer material - it is not.
To the OP, if you are still searching for a case,
this is the one I am currently using. It's about the closest I've ever found to what you want. I too am searching for the case that fits your criteria, so if you find a better one, please post it. Scroll down in that thread to see my comments after receiving it.
