Can anyone recommend an l2arc m.2 drive? How big dose it really need to be and how fast ?

tl;dr: You probably don't need one.

 

Max out RAM first if you're concerned, but basically a home user (or even most business/industrial data storage applications) won't ever benefit from it. It's really only useful if you have a single random-access data-source that's larger than the system RAM allocation.
