I would never recomend a Kiev to a newbie. There are too many factors and it is easy to get frustrated. There are good ones out there but you have to have to have patience. There are people who go through five maybe six cameras before they quit or get a good one. Plus the price can get high as you get upgraded cameras.
Arax can replace your shutter if you have the inclination but there is really nothing wrong with cloth. Just remember to cock the shutter after the shot. It is possible to burn a hole in it if the sun shines right through the lens.
