>what are you driving with it
Not driving anything but my 1M scope probe. It's running off my function generator.
>opamp stability tends to be lower near unity gain than at higher gains
I didn't know that. I'm trying it at a gain of 10 now, with a pair of 10ks and a 1µ as my virtual ground. The oscillation is gone, and so is all the gain, it's acting very strangely now, pic related being input and output respectively.

I've noticed that in all my experiments the output impedance is acting really low, because just touching the output is causing it to quiver, while touching the input does nothing at all.

>a lower voltage part
I'll definitely consider it.
