I'll start by saying, yes, this is my first time posting here (but then again, I think every negative comment in this thread is also the first and only comment by the user in these forums).
I found this thread when I was looking into CamerasAndParts.com, and now that I've dealt with them thought I'd add my own experience. Like some others, I've had the experience of sending in a fairly expensive camera (a G9), and not hearing anything back for a while. There is always some delay -- sometimes several days -- between sending and email and getting a response, and often the response doesn't really explain what is going on. So it can start to feel like a scam. But after sending several complaints, threatening to file a payment dispute, etc. a manager called and explained exactly what was going on with the delay (the camera required additional repairs, including a new logic board). He explained that they had undertaken these additional repairs at no extra charge -- and, although he didn't say this, their price is already 50% lower than most camera repair places.
The manager said that usually cameras are repaired and returned within 2 weeks.
One thing that set my mind at ease somewhat while I waited two months for a camera and hoped I didn't send it into a black hole, is that the company has an A rating with the Better Business Bureau of El Paso. (The manager pointed out to me that even Canon only has a C rating with BBB, and most other repair places are much worse.)
At this point, I can say that you can trust these guys and they'll get your camera repaired at lower price than most other places. But if you want really good customer service, you may want to pay extra and go to a local camera repair shop.
