broken radiator

Has anybody elses radiator in their Odyssey sprung a leak? My lower radiator tank rotted away. Now I need a new radiator. Is this common?
Mine is a 97.

Check local radiator shops, they may be able to just replace the plastic lower tank. I have a small hole/crack in my top tank (my Oddy is a 1995), and am having a local shop replace the tank. I found new radiators through Honda/Isuzu parts for like $170, but it's only costing about $60 to have the tank replaced (me removing the radiator).
