I need a rail-to-rail I/O OpAmp, 5V Vcc is fine, slow speed setting a

What specs?
What would you guys in the discrete world recommend as being
well-behaved, no peculiarities, etc? (And readily available ;-)
I've been using the MicroChip MCP6294, mainly because they're cheap
but the specs matter.
That looks OK for non-critical stuff. The single MCP6291 in SOT23 is
around 40 cents in quantity. (I like singles, usually.) Somewhere
there ought to be a really cheap workhorse opamp, ten cents maybe.
Already exists. LM358, $0.09 in quantity 1 from Newark. And it's a
dual!

I love to cook with wine. Sometimes I even put it in the food.
