B&H Photo is now carrying Yongnuo products. This includes the 50mm f/1.8 clone that has received a lot of press recently. Some are saying it's actually better than the Canon lens it copied. That lens isn't currently in stock, but a lot of their very inexpensive flashes are.
I have no personal experience with any of their products, but if you do, please comment in the forum thread for this post.
