Slight modification to a theme
You get what you pay for....

Add the following....
You buy high end parts
You use high end tools
You buy the best of every thing

Multiply the sum of the above by the lesser of the following
paid attention to detail
researched what you are doing and evaluated differences
Knows how to use the special tools if needed

When you take the top and multiply by the bottom set and the bottom has a
zero, the top is meaningless except to the wallet.  I know someone that is
screaming in agony right now because of severe pain in the hip pocket area.

In my years of doing this stuff, in my younger days I will admit to having
been there on projects.  Fortunately my errors were inverse to the cost.
The higher the cost the less chance I was going to make an error in the
bottom items.

Planned insanity is best.
Remember that sanity is optional.
