SMD jfet for buffer

[garfo]

Hello everyone. Every time I'm in a pickle, I find it very useful to reach out here for other people's experiences and knowledge.
Having said this I would like to  know what options are out there for an smd JFET to be used as a buffer. It will be replacing an opamp and my aim is for it to be low current draw (what I'm using now is about 0.45 mA, so it should ideally be lower). As it will be a buffer, it should be able to take hotter signals as well.
I thought the mpf102 was the way to go, but it doesn't appear to exist in an smd format.
Hopefully someone can help with some useful information.
