And the Limited Edition was $139.99 when I got one in late 2012. I think I got my original one in 1982 for under $100, because I got two discounts. When I went to the Caltech bookstore to buy one they were sold out, but had one for display that people could try out. They said I could buy that one at a discount. There were no signs of any wear or abuse from the people who had tried it, so I was willing to buy it. But I noticed that it was using comma instead of period for the decimal point, and period instead of comma for the group separator. Neither I nor the salesperson knew that there was a setting to swap these. We though it must either be defective, or somehow the store had actually been sent a model went for one of the countries that uses that convention. The store offered me another discount because of that swap. I thought a while and decided that I could get used to it, and accepted.
