In fact, my coil started acting up on my summer house and I put a super stor in, worth every penny in my opinion. That was about 6 years ago, old boiler is still going strong. But if money is an issue, I would have the coil cleaned and put a new mixing valve in.
I don't believe in replacing boilers until they start leaking, any increase in efficiency is small compared to the cost of replacement. I like to get every last penny out of stuff.

My oil consumption went way down after replacing my 30 year old boiler. I estimate a five year payback after seeing my oil bill drop this winter and this winter was much colder than the year before. And oil was more expensive this winter than the year before. Since it's a second home I sleep better not worrying about a 30 year old boiler crapping out and my place freezing up. To each his own.
