"It's unwise to pay too much, but it's worse to pay too little. Whenyou pay too much, you lose a little money - that's all. When you paytoo little, you sometimes lose everything, because the thing youbought was incapable of doing the thing it was bought to do. Thecommon law of business balance prohibits paying a little and getting alot - it can't be done. If you deal with the lowest bidder, it is wellto add something for the risk you run, and if you do that you willhave enough to pay for something better."
