It's unwise to pay too much,
but it's worse to pay too little.
When you pay to much,
you lose a little money ... that is all.
When you pay too little,
you sometimes lose everything
because the thing you bought
was incapable of doing
the thing it was bought to do.
The common law of business balance
prohibits paying a little and getting a lot...
it can't be done.
If you deal with the lowest bidder,
it is well to add something for the risk you run,
and if you do that you will have enough
to pay for something better.
