The moral of the story "It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that's 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 can't 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."
John Ruskin

Well, in that craziness we see genius and that's who we make the world's smallest programmable RPN calculators ever for.
