The attached plot shows the sort of improvement in warm up time and 
stability of a simple "oven" made by attaching a Darlington heater 
transistor and thermistor to a Crystek 100 MHz oscillator, adjusted to 
set the osc temp to around 35C and wrapping it all in foam.  In this 
application, a DDS clock for an HF transceiver, the result was well 
worthwhile.
