Gas and Oil Home Heating Furnaces - Replace Gas Fired Boiler Hot Water System?

Now that the weather in the good old Pacific Northwest is beginning to change the new heating season is almost upon us. My gas fired hot water heating system (4 zones) is 33years old and heats our 2800 sq. ft. home through hot water panals located throughout. I shut it down earlier than usual last Spring because it was failing, heating only 2 zones. Also, the pressurized tank began dripping water. My options are to fix this system as best I can to get me through the Winter, or to replace it with a new state of the art gas fired hot water system. If I replace it, what brands are out there that would give me a great system with all of the economies I might expect?? Suggestions please...
