If low noise is of major concern those opamps are definitely worth a try.Werner said:OPA2227 and 2228. 3nV/sqrt(Hz).

Not sure if it will suit your requirements, but Brown Dog make a converter that will allow you to mount two single SMD or DIP op amps to make a dual op amp DIP package. I am using these to construct an active crossover using OPA627 single op amps (the pcb I have uses dual op amp DIP).
