I'm a committed amateur city-scape photographer who is looking for a good DSLR. I'd prefer a Nikon or a Canon. I've done all the research and read the reviews but it's all conflicting! Can anyone help? Here's what I'm looking for: I want a steady workhorse in the $500-600 range (USA), used. That should include a decent 18-200mm name brand lens. I'm not looking to change the lens often. Thus, it needs to be good at adapting to different situations. I intend to take it outside often so it should be fairly weatherproof. I'm not too concerned with how much it weighs considering that the love of my photographic life was my Canon A1. It must have an autofocus option and be above 8 megapixel. I'm not a megapixel snob I simply want to be able to get crisp prints in fairly large sizes. Any ideas?
