"It's unwise to pay too much but it's worse to pay too little. When you pay too much, you loose a little money - that's all. When you pay too little you sometimes lose everything because the thing you brought 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 cannot be done. If you deal with the lowest bidder, it's well to add something to the risk you run and if you do that you will have enough to pay for something better."

John Ruskin 1818.
