I got a bunch of stuff when I first started that were really helpful!
My favorite and number one pick is Barry Zundel's Animation Master Training DVDs. Doesn't look like he offers the DVDs anymore, but you can buy the videos for download
here. By far, I learned the most from these.
Jeff Lew's DVDs are
here. Good action stuff and done in a really entertaining style. I need to watch these again, since it's been a looong time.
In the M.I.A. section are:
Christin McKee's "Animate!" CDs and Justin Barrett's "Animate a Face!" both from Anzovin and sadly no longer available.
Will Sutton's "Decaling/UV Setup," "Smartskin/CP Weights" and "Patch Modeling" that were all very useful and informative, but also aren't for sale anymore.
Anzovin's TSM2 was made available for free here on these forums. Do a search for it.
For my money, Barry's video tutorials are the best money spent. He takes you through the interface, modeling and rigging a character and animating, giving tips and insights that really turned things around for me.
