Default Good alternative to AD817/825 in Jung regulator?

I am in the process of building 8 Jung/ALW super regulators. Farnell/CPC and RS components don't seem to stock the 817, Newark a part of Farnell stock them, but I refuse to pay an additional 15 for PnP just for a few opamps.

Are there any alternatives? I've got a few AD797s on hand, but they can suffer from stability issues it seems.

Many thanks Matt.

I have read that opa228 performs well in low noise situations where 797 were specified.
This may be a case where it could do an adequate job. They are surprisingly cheap for the spec they achieve. Also available as dual 2228 and quad 4228 and unitygain 227, 2227, 4227.
