One of the cliches in life that is actually quite true. Of course, if you only need something for a short period of time, there's no need to buy the best. However, if you want something to give you pleasure for the long haul, do your research and buy the best you can for the money.
Example: Cars . . . . A Yugo will get you there for six months before it breaks. Hondas, for only half again as much, will last forever.
