I'm really starting an interest in more advanced photography. A local place has a used Canon TI with a 28-300mm lens for 450+tax... it probably doesn't come with the books or the wire or any of that. it has a lens cover on it and a very nice hefty looking canon neck strap. would this be a good entry level camera? or should i save and get a rebel XTI or a d40 instead? i'm researching my options right now, but i bet you guys have far more knowledge about this kind of thing than i. please shine some light my way.
