If a machine is the only one that can perform a needed function, it would be desirable regardless of price. Also, price should be irrelevant for any machine that can do a needed function. What matters in these two cases is that the function be performed, regardless of the relative difference between the two machines. Thus, if time keeping is the only prerequisite, an expensive Brietling original is just as good as a Breitling replica.
The same analogy can be applied to shoes and apparel. However, there are other considerations worth mentioning. Firstly, for dress shoes and apparel like Christian Louboutin, style is paramount. Patrons tend to ignore other considerations like cost if the style suits them. The second consideration applicable to sport Adidas shoes and apparel, like Adidas, is comfort. Uncomfortable shoes or clothes may severely affect the athletes performance. Note that for Christian Louboutin, comfort comes secondary and for Breitling Replica watches, comfort is not an issue. Also, since Breitling Replica watches look exactly like an original, style is exactly the same.
