After all this advice and seeing what others use, I have decided not to install anything.
Why you ask?
Drilling holes is out of the question for one.
I would be constantly watching any meter and getting drove crazy when it would change in the least.
My family says I have a bit of OCD.
They may be correct now that I see how the above things mentioned would bother me.
Sorry for wasting everyone's time.
I can explain it to you, but I can't understand it for you.
