I found this one recommended on another site and thought for $10 it was worth checking out. I received it today and it really fits well on the phone and barely adds any size to the unit. Here are the pictures and a link to where I bought it from.
1) I put it on and took it off and it looks like it does not scratch or damage the phone in any way.
2) you can also add a belt clip (see square hole on the back of the case.
3) I am able to reach all buttons, stylus, etc with no issues at all.
UPDATE - This case causes some problems. After having it on for a few days the screen stopped working when the cover was on. From my investigating it seems to put to much pressure on the upper left corner of the case/screen, causing the screen to stop responding to touch commands. I would not recommend this case, even for $10..... I have taken the case off and there are no issues at all with the phone, so clearly the case is the problem.
