I like this website because it covers a large variety of skills. You rent videos, much like on Netflix, except these are instructional. These videos are reasonably priced and high quality. With 5623 videos in 227 categories, there is something for just about everyone. Subjects include arts and crafts, aircraft piloting, calculus, clocks, construction, culinary, business and marketing, metalworking, glassblowing, home remodeling, software training, webdesign, and more.
