There just are no jackets that are breathable, insulated, waterproof, well ventilated, etc. My suggestion would be to get a nice, fairly windproof, but NOT waterproof jacket, a windproof vest, and a waterproof rain jacket. Between those three, a base layer, and a jersery, you'll have everything you need comfortably, without any excess weight.
I agree with the layering approach. On tour my tops include 2x midweight long sleeve wool Ts, the Marmot Driclime and an O2 rain jacket. In warm weather it's just a wool T, if it rains I use the O2, if it goes below 60F the Driclime goes on if it rains lightly the Driclime can handle it, but for heavy rain the O2 goes on. If the temp approaches freezing I'll put both Ts on and the Driclime.
