I decided to purchase the tool.
Here is the updated link as they do not reference themselves as Nissantechmate any longer, but both web links function.
Part # NI-48761
Oddly, I could not register an account - as both website links have a bug in it - in ordering anything to Ontario, Canada. (every US State and every other Canadian province was there)
I called them directly, ordered it. Very good service from them on this.
