To build a low-wattage substrate heater which generates about 1
watt/foot of heat, it might be sufficient to just use airline tubing
or something similar as insulator, as Steve Pushak suggested.  Do you
have any numbers on the range of resistances/unit length that is
avaialble?  How much does nichrome wire cost?  And where can one find it?
