Hi, I am curious if I should purchase a Canon 40D body with 8k shutter actuations for $600. It comes with battery, strap, charger, cd's but no box, and a rubber armor. It is still under warranty, and the seller has receipt. Not sure if it has been registered. Is this a good deal? A great deal? or just an average deal. Feel free to ask anymore questions. Also wondering what would be a good suggested first lens. I am interested in the Sigma 10-22mm wide angle. I am going to use this camera to mostly shoot weddings. Any other suggestions for lenses or anything please let me know. Thanks!
