The type of window blind that is best depends on your taste, budget, and location. Take into consideration factors like natural light, where your building is located (i.e. is it private?), your personal style, and the climate. Wood blinds are the highest quality and most expensive. Vinyl blinds are usually the least expensive. However, if the blinds need to be functional, as well as decorative, certain types of vinyl can cost more -- for example, blackout blinds (for bedrooms that get a lot of early-morning natural light) or insulating blinds (in regions that get very cold during certain seasons). Aluminum mini-blinds are an extremely versatile and popular style of blind in the mid-range price category if there are not special conditions, i.e. extreme weather possibilities.
