I hate the way the UAG case looks. I'm sure it protects very well, but I'm generally very careful and I've never broken or even significantly damaged a phone before. I despise the look of the fake plastic bolts on the back of it.
My vote goes to this case made by "Tridea". Someone else mentioned it on here, and I got one. It is a really great case, fits perfectly, is dirt cheap, and it comes in a ton of colors. It adds a little bit of bulk to the phone, but probably less than the UAG case. I'd easily pay $30 for this case, but it's only $10.
I got the brown leather one. True, it is a fake leather pattern, but it looks much more convincing than any $10 case has any right to. It looks just like the photo on Amazon, that's not a trumped up studio kind of photo.
