I bought an A3000 pentax in highschool from a local pawnshop. It has a vertical line through every picture I develop, regardless of the lense. I'm going to buy another camera off of ebay, and would like to buy another pentax so I can use all of my lenses. What would be a good choice of a newer chassis? Most all of my photography is outdoors, ie rodeos, car races, wildlife, etc. Any advice would be greatly appreciated. I don't have to buy a brand new camera, just something that operates well, and isn't made out of porcelain. Thanks.
