"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. When you pay too little, you sometimes lose everything, because the thing you brought was incapable of doing the thing you brought it to do. The common law of business balance prohibits paying too little and getting a lot - it cannot be done! So if you deal with the lowest bidder, it is wise to add something for the risk you run. And if you do that, you will have enough to pay for something better." John Ruskin. 1819 -1900,
