If you would like some awesome and affordable online art education, I highly recommend the recently started New Master Academy. I've been trying it out for a few months now, and while the quality varies a bit from lesson to lesson, overall it is an amazing value. I've spent hundreds on art DVD's in past. Generally, you can expect a 2 hour demonstration video from a professional artist to cost $30-$100. Compare that to the $19 monthly subscription for an ever growing list of video demonstrations and lectures. You really can't beat that.
The videos from Steve Huston alone make this a good value IMO.
Hopefully these guys are successful, so that we see more content like this in the future.
