Hi everyone, i'm a big newb when it comes to electronics, and i'm currently a poor undergrad :er:. I was looking for something compact and small to take pictures with (nothing serious, just photos for going out and for traveling), and someone told me about keh.com. I was looking at the sony dsc-t7, which is discontinued (on keh, they have it for a sweet price). I've read reviews over the site, and most of them were pretty good. However, the camera is rated as EX. What kind of condition should i expect it to be in? And what does dust in the glass mean, is it fixable? I'm sorr to ask so many newbie questions, but i just wanted to get a second opinion before i go out and buy it from keh. Maybe i could take it into a camera store like wolf camera and let them look at it? I appreciate any input!
