I have calculated everything 5 or 6 times and everything is going to work out okay. The price of the Z16 is up by $.65 each, but I scrounged around my office and shop and found some leftover labels and enough shipping and packing materials to almost offset the increase.
I am going to order the parts today. Hopefully, the lead times on 2 backorders will be less than stated.
I appreciate all the offers to purchase more controllers.
I will keep you all posted.
