Does it need to be rail-to-rail?

If not, I'm partial to the LT1013 (dual op-amp in standard DIP8 or 
SOIC8 packages).  I normally use it in single-supply mode, with the 
op-amps powered from my unregulated supply.  This lets me get input 
and output swings that cover the full dynamic range of the a/d inputs 
that I am feeding.

Be sure to purchase (or at least price out) the TI version as opposed 
to the Linear Technology version - price difference is significant 
(TI: $0.80, LT: $4.35)
