Product shortages.

 One result of the devastation in Japan will be product shortages. As we well know, Japan is a primary source for semi conductors, circuits etc which make our music systems work. Many of the large manufacturers such as Yamaha and Sony have closed factories and are in the process of re-building.  Many manufacturers have already announced price increases some of which are immediate, others loom. It may be worth while to purchase product sooner than later in order to avoid additional costs.
