Product review (3 stars): Did the job...
This was advertised as being "used, very good."  And it was replacing a used but not-so-good oven brain.  It was an exact match; just unplugged and removed the old one, put the new one in.  The missus no longer has an excuse to not bake cupcakes for me.  (I thought about replacing the entire range, since it's 12 years old or so... but a $70 brain is much cheaper than a $550 range.  Hopefully we can get another couple years of life out of the oldie.)
