The cost of a heat exchanger is a small piece of the total install. A boiler like mine can be found for $3000-$5000 used/refurbished; the cost will depend on age, condition, and included accessories. A new EFM like mine is about 9 grand (last I checked). There are other units available such as Leisure Line, Keystoker, AHS, Axeman Anderson, Coal Jack, etc. Some are auger fed, some have a hopper, some have an adjustable btu output, some don't...what works best for you will probably depend on the heating load of your house, and how much you want to spend.
Do you have a chimney available and room in the basement? A walk-out basement is ideal for coal.
