If you have a crack in the exchanger you will have to replace the exchanger at a minimum (an individual burner cell at the least or the entire section if its a one piece assembly style exchanger) or the complete furnace at the ideal.
Replacing the exchanger will most likely only give you a one year warranty on the replaced part. Replacing the furnace as a whole will give you 10-20 years warranty on the exchanger, one year on all associated parts (blower motor, wheel, board, ignitor, etc). Furthermore, you can take advantage of higher efficiencies that were unheard of 20 years ago at reasonable prices.
Either way, a cracked cell is a monoxide hazard that can cost someone their life. Also, a crack in the exchanger can allow air forced through the unit by the indoor blower into the burner section through the crack, a back draft, which will cause the flame to roll out of the unit into the cabinet - a serious fire hazzard.
It really stinks that you have that issue; however, anyone in the industry will tell you the exact same thing I just told you. Your furnace has met and is exceeding its service life expectation by any industry standard.
Just a thought.
