Ok, revised my letter. Replace the second paragraph with:

Attached is a copy of my receipt; the camera should still be under warranty. Since this is the second instance of this problem, what can be done to ensure it won’t happen again? I have done extensive research online and have not seen any reviews or mentions of the Cool Pix 4300 encountering this problem. I have been very impressed with the camera’s performance, and the efficiency of your support and service teams. It seems as if this problem is unique to my camera, and I was wondering if there is any way possible that I could have a replacement camera to avoid such a problem again?

Too forward? Wahhh! I love my camera, but hate this part!
