For this blog I bought a cheap, $25 digital camera so I could keep a camera in my purse that runs on batteries. Unfortunately, the camera took terrible pictures and the flash pretty much didn't work. So I found a camera on Craig's List for $45 and it works great. It is bigger than I'd like but I figure if I really use it all the time and feel commited to the blog I can sell this one on Craig's List and get a smaller one down the road.
Here's the first picture I took with it (much clearer than the other blog pics I've taken!)
