I have a Pi Zero with case if thats of any interest.  It doesn't have wifi but I also have a usb 3 to eithernet adaptor that goes with it.  It was my PiHole before I upgraded to a 3b (that didn't block ads any better than the zero).

I have 5  sitting here with new  official power supplies and in official red and white cases. 

$50 each excluding shipping. (I think that is a fair price correct me if I am wrong).

If you are in chch more than happy to have them picked up :-) , Same goes to anybody else that may be interested in one.
