What is bad buying an used camera Nikon D60?

Is it good idea purchasing Nikon D60 for $350 and 2 year warranty?
My teacher knows a lady who's daughter is selling a nikon D60 slr camera for $350 with original receipt included, all the package with straps, lenses included, plus two year warranty and one year of using camera. I was wondering is it good idea doing so? I know that my teacher knows that lady who's selling the item, plus I talked to lady only on the phone, and I think next week I will be purchasing the camera. I'm not good at cameras at all, plus it would be my first slr camera. Although I have money to buy something new like Nikon D90 or Canon T1i, which those both can shoot video and have other great features. The camera originally cost $750 with three year warranty. What should I look in buying an used camera nikon?

It sounds like a good deal to me!

I'd much rather buy a used camera from somebody I knew (or a friend of a friend) than buy one from a stranger.

Bottom line is that if the camera looks like it has been cared for, it probably has been. Make sure that there isn't any evidence that the camera has been dropped (cracks or major scratches). Take the lens off and look at the mirror, and make sure that looks nice and clean. Make sure that flash pops up and goes off (you might need to take it to a dark place for the camera to want to use the flash). Ask the owner what the shutter count is.these cameras are pretty durable overall, but the stated life expectancy for the shutter is about 50, 000 clicks. How much you plan to use it will determine how close you can get before you decide you'd rather have something newer. Finally, take a few pictures with it if you can and look at the results.

The Nikon D60 is an okay camera but it is getting kind of old. The Nikon D3000 and D3100 have replaced it. In additional, the D90, D5000 are better and the D7000 is the replacement for the D90. Finally, who is warranting the camera? As far as I know Nikon warranties are not transferable.
