What? You mean not everyone has been doing electronics soldering regularly for the past 27 years?

Ok, maybe not the best solution for everyone.

pHaestus,

The ONLY way to eliminate error with thermistors resulting from lead length, is to use a four wire (Kelvin) connection, where one pair of wires is carrying the current for the thermistor and another pair of wires brings out the voltage across the thermistor.

A four wire connection using 40 gauge wire, is likely to be better than a two wire connection using 24 gauge wire. Of course this doesn't do much for you if you are hooking up to something with no provisions for four wire readings...
