You can easily find a +3 FB staff from Drognan (Act 2) and socket it yourself. He can probably sell them with 4 sockets but it has to be rare.
You can buy +3 FB white staff in A1,2 and 3 in normal. (You have to be clvl 19 or below in A3)
They will never have more than 3 sockets if they're grey, but can be socketed to 4 sockets if white.
A rare staff would never have more than 2 sockets, and you can't shop rare items of course.
I can see a great use for a 2 socket fb staff for leaf early doors, but not sure it's ever really worth it to make insight or memory in a 4 socket one.
