I just got a used 10D and a 70-200 2.8 IS. The main reason I got this package is because I really wanted the lens and the seller wouldn't separate the two.
I figured I'd buy the package and sell the body.
Both items appear to be in great shape.

I tested the camera and I don't know if I'll keep it or not.
But I must say that I like it a lot. It's very quiet compared to my A2.
However, there what apear to be dust spots on the sensor.
Frustrating, but I don't think is the end of the world.
I'll have to deal with this weather I sell it or keep it.

I saw images taken with his camera from the seller and I did not see any problems with the images.

The seller was an older man in his late 70's so he may have not noticed the dust spots.
Although he "guaranteed" the package, I'm really not leaning towards contacting him about it. What do you think?

Have any of you had to deal with this or have any suggestions?

Shoud I send it to Canon $$$ or is this something that I could handle myself with the right cleaning tools.

Can I get these tools from a Rits or Cutler camera?
Thoughts or comments appreciated.
Thanks is advance.

Just thougt I'd mention the fact that the mirror itself does appear to have dust on it. Should I attempt to clean the mirror prior to cleaning the sensor?

dust on the mirror is not that important. When you take a picture the mirror swings up out of the way so light can his the CMOS chip. The dust on the mirror will not effect your pictures in any way.

Dust on the sensor can usually be cleaned with a blower. Ritz sells them or you can get one in the infant section at Walmart for a buck or two. There is a special cleaning mode to put the camera in. Read the instruction manual first and you'll be fine. But never, touch the chip (actually there is a filter in front of the chip that you clean.)

Hi Bernard,

Here are 2 articles you should read:

http://www.bythom.com/cleaning.htm & http://www.pbase.com/image/15473243 - I have a D70 myself but have not needed to clean the sensors (yet).

For Jeff, Ken and the others with D-SLRs.
How often do you find you need to clean the sensor?

One addendum to Jeff's suggestions...

Do not be tempted to use canned air to dislodge the dust. Please use only a hand-operated blower.

By "cleaning the sensors" I assume you mean some form of physical contact with the sensors, rather than simply a good blow(er) job, eh?

To-date, I have only found the need to perform such a cleaning once on each of my DSLR's. I generally use a blower on them relatively frequently, particularly after having changed lenses a few times. (I use a Giotto Rocket blower. It's pretty powerful and quite well designed.)

Thanks to all who replied. I followed Jeff's advice. I knew not to use compressed air. I had one of those hand pressed air pumps and it worked great!. I haappen to have one of those thingys that I used to clean my other camera.
I took literally one minute.
I did not want to get into brushing or wiping the sensor if I didn't have to so again, Thanks Jeff and all who replied
