Oops, my apologies, got focused on the hacking the pan apart bit & forgot the 
Mega128 ;-)

One of the commercial proto ovens uses this.  The hotplate forms the board 
support & substrate heater. The fans circulate the heat around the oven cavity 
from beneath the plate. Above the PCB is a set of quartz bars, pyrex window in 
the top.
