Satisfied 10D owner surprised at complaints.

I am the satisfied owner of a 10D since about a month after it's release in 2003. As I live in East-Africa this camera had to endure a lot of hardships from bumpy roads to dust and rain. The rain is no problem and this camera has done a lot of work out in the wet. Dust is a problem though and have been living with dust specs on my sensor for years now. Tried countless times to clean but never succeeded. I am surprised at the amount of complaints about image sharpness/focus. I am very satisfied with the quality of my images. I never use auto settings or auto focus and operate the camera on manual with good canon lenses. I am planning to upgrade to another higher specked body but will always keep the 10D as a backup as I trust this camera and it has served me well. This is a great workhorse.
