Hello, my brother is welling to buy some studio lighting, so what's the best soft boxes and flashes to buy? And what's good but not the best? What's the difference between the "lights" and the "flashes" and which one is better? And what do you think about this kit in this link? http://a763.g.akamai.net/7/763/1644/3/app.infopia.com/img/image/fp/VPID/3767218/img3/img.jpg Help please!
