It is unwise to pay too much, but it is worse to pay too little.
When you pay too 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 the thing
it was bought to do.

The common law of business balances 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.

There is hardly anything in the world that someone can't make
a little worse and sell a little cheaper - and the people who
consider price alone are this man's lawful prey.

-John Ruskin (1819 - 1900)
