David, you put the heating kit on. Given that it's been nearly 14 years and 65K, should I sweat (get it, "sweat"?) it?

I'm certainly not adverse to the extra $355, but would you call that a "fix" or a "partial alleviation"? Is the pan heater a better solution, given that he'll be down there anyway? If so, do you have a link to one?

Thanks for all of your help, everyone!
