I know I have mentioned this person before in a post, but I have to mention him again; AMB Animation Academy. His tutorials are top notch and he gives away free, what many schools would charge for. Please check him out at his YouTube page linked above.
Also, for the past couple months I have been using and thoroughly enjoying the lessons from Toonboxstudio by Paris Christou on YouTube. Wow! If you like to draw and want to improve your skills for animating, drawing cartoons or comics, then check him out. He also has some paid lessons at his site http://toonboxstudio.com/
which are very inexpensive and fantastic! Some are 8 or 9 hours of videos for $27!! Can't beat it folks! He uses AutoDesk Sketchbook Pro and has some videos on its features. I purchased the software and am loving it. Getting a tablet for Christmas so I am really going to be making the most of it. Software is cheap, $55 from Amazon. You can go to the site and get a demo version as well. sketchbook-pro/overview
There are also some great videos from Tom Bancroft and others at http://taughtbyapro.com/
Some real good lessons to absorb.
