I just picked up this Giottos rocket air blower from adorama.com. The materials used are very high quality and the item feels very durable. It has an air valve to prevent it from sucking in dust and blows out a powerful blast of air to blow dust away, to make cleaning your camera, lenses, or filters really easy. The Giottos rocket is a great value for a piece of cleaning equipment. I trust it with my Canon 7D and L lenses.
