Check this out I found this copied and posted on my auto mechanics wall while waiting for an oil change. "It is unwise to pay too much, but it is worse to pay too little. When you pay too much, you loose 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 cannot 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."
