Adi, I like the LMC660 (quad) and LMC662 (dual) for buffering
sensors. It has a rail-rail output swing, 3mv offset, 0.002pA input
bias, and works with single supplies up to 16V or dual supplies.
It's pin compatible with the LM324, LM358, etc. It's faily cheap
and is widely available. See National's web site for more info:
