It is unwise to pay too much but worse still to pay too little.
When you pay too much you lose some money it is true, but that’s all. When you pay too little you risk losing everything because what you have purchased is not able to do the job you bought it for. Common commercial law does not allow the possibility of paying little and getting a lot: this cannot happen. If you deal with the cheapest then you need to keep something back to cover you for the risks you take. If you can do this you will certainly have enough money to buy something better
John Ruskin (1819 – 1900)
