Just a suggestion, but if you buy a good fan and they install it properly, it should last you for a really, really, really long time. Too often, people buy the cheapest ones, or the fan doesn't get "balanced" when it is installed and then they are replacing them 5 years later. If properly installed, the fan should not shake when it is on high. If it wobbles, it is not properly installed.
