Buy an appliance only in a reputed shop, which guarantees after-sales-service for a year or two. Go for brand names which you know last for years, because your initial investment will be high.

Before you go to a store to buy an appliance, collect literature about the appliance from various shops or companies. Check out which model has the features that you want and be prepared for the prices. If you are unprepared, you could end up paying more for features or accessories that you may never use. Buying well-known brand names ensures quality of parts and the product as a whole, and also genuine guarantees. Make sure that the warranty covers the whole product, including the parts which may be hard to obtain later on or are the most expensive.
