Been buying equipment from B&H since 2001, starting with underwater video equipment, then land camera parts, video and recently computer, lighting and audio kit. They have a great range of equipment, with good descriptions, and user reviews. That makes it easier to decide if the part is the right one and if it is really for you. I also like the PAPER copy of their product catalogue, sent in the mail 3/4 times each year; it makes it easier to find items, and is also great to browse through to keep up to date with photographic equipment.
