Just saw the OPA2277, enhanced dual OP-77. Haven't tried one but they
look very good for expo and CV summers. Made by Burr-Brown, and in the
UK stocked by Farnell at 2-00UKP each.

I also like the OP-275, ADs dual audio opamp. Better than 5532, about
the same price, and much better offset specs.

I also like the OP-42 high speed precision FET op-amp, bit expensive,
but good for accurate I-V at the back end of fast DACs.
